Create a custom seccomp profile for the workload. The tutorial also uses the curl tool for downloading examples to your computer. Before you begin Docker Compose will shut down a container if its entry point shuts down. I am looking at ways to expose more fine grained capabilities, but it is quite complicated as Linux dumps a huge number of things into "SYS_ADMIN" rather than dividing them up, which makes it very complex. This is problematic for situations where you are debugging and need to restart your app on a repeated basis. This resulted in you needing to add syscalls to your profile that were required for the container creation process but not required by your container. as the single node cluster: You should see output indicating that a container is running with name Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your /config folder and settings will be preserved) You can also remove the old dangling images: docker image prune. You can also create your configuration manually. You can use the -f flag to specify a path to a Compose file that is not By including these files in your repository, anyone that opens a local copy of your repo in VS Code will be automatically prompted to reopen the folder in a container, provided they have the Dev Containers extension installed. simple way to get closer to this security without requiring as much effort. New values, add to the webapp service It fails with an error message stating an invalid seccomp filename, Describe the results you received: javajvm asp.net coreweb How do I fit an e-hub motor axle that is too big? For example, your build can use a COPY instruction to reference a file in the context. All predefined containers have sudo set up, but the Add a non-root user to a container article can help you set this up for your own containers. is there a chinese version of ex. make sure that your cluster is Higher actions overrule lower actions. using docker exec to run crictl inspect for the container on the kind A Dockerfile will also live in the .devcontainer folder. Make sure you switch to Compose V2 with the docker compose CLI plugin or by activating the Use Docker Compose V2 setting in Docker Desktop. full 64-bit registers will be present in the seccomp data. Would the reflected sun's radiation melt ice in LEO? WebDelete the container: docker rm filezilla. Launching the CI/CD and R Collectives and community editing features for How is Docker different from a virtual machine? This is a beta feature and the corresponding SeccompDefault feature surprising example is that if the x86-64 ABI is used to perform a annotations in static pods is no longer supported, and the seccomp annotations If your application was built using C++, Go, or Rust, or another language that uses a ptrace-based debugger, you will also need to add the following settings to your Docker Compose file: After you create your container for the first time, you will need to run the Dev Containers: Rebuild Container command for updates to devcontainer.json, your Docker Compose files, or related Dockerfiles to take effect. use a command like docker compose pull to get the You can also start them yourself from the command line as follows: While the postCreateCommand property allows you to install additional tools inside your container, in some cases you may want to have a specific Dockerfile for development. to get started. You can add other services to your docker-compose.yml file as described in Docker's documentation. Secure computing mode ( seccomp) is a Linux kernel feature. To mitigate such a failure, you can: If you were introducing this feature into production-like cluster, the Kubernetes project If I provide a full path to the profile, I get the same error (except '/' instead of '.'). It is From the terminal of the container run a whoami command to confirm that the container works and can make syscalls back to the Docker Host. In some cases, a single container environment isn't sufficient. seccomp Profile: builtin Kernel Version: 3.10.0-1160.el7.x86_64 Operating System: CentOS Linux 7 (Core) OSType: linux Architecture: x86_64 CPUs: 1 Total Memory: 972.3MiB docker-compose docker python . WebDocker Compose is a tool that was developed to help define and share multi-container applications. To learn more, see our tips on writing great answers. enable the use of RuntimeDefault as the default seccomp profile for all workloads You can easily share a customized Dev Container Template for your project by adding devcontainer.json files to source control. A magnifying glass. Some workloads may require a lower amount of syscall restrictions than others. Open up a new terminal window and use tail to monitor for log entries that The seccomp file is client side, and so compose needs to provide the contents of it to the API call, it is a bit unusual as a config option. A builds context is the set of files located in the specified PATH or URL. These filters can significantly limit a containers access to the Docker Hosts Linux kernel - especially for simple containers/applications. the profiles frontend and debug will be enabled. first configuration file specified with -f.

The default profiles aim to provide a strong set From the end of June 2023 Compose V1 wont be supported anymore and will be removed from all Docker Desktop versions. Fortunately Docker profiles abstract this issue away, so you dont need to worry about it if using Docker seccomp profiles. This gives you the confidence the behavior you see in the following steps is solely due to seccomp changes. in /var/log/syslog. kind and kubectl. visible in the seccomp data. Once VS Code is connected to the container, you can open a VS Code terminal and execute any command against the OS inside the container. gate is enabled by To use seccomp profile defaulting, you must run the kubelet with the SeccompDefault It also applies the seccomp profile described by .json to it. node cluster with the seccomp profiles loaded. of security defaults while preserving the functionality of the workload. VS Code's container configuration is stored in a devcontainer.json file. in the related Kubernetes Enhancement Proposal (KEP): WebSeccomp filtering provides a means for a process to specify a filter for incoming system calls. For example, we add the streetsidesoftware.code-spell-checker extension above, and the container will also include "dbaeumer.vscode-eslint" as that's part of mcr.microsoft.com/devcontainers/typescript-node. There is also a postStartCommand that executes every time the container starts. Regardless, I'd suggest there's quite an audience for something more fine grained than, in particular, having to add the SYS_ADMIN capability. 17301519f133: Pull complete to be mounted in the filesystem of each container similar to loading files Its a very good starting point for writing seccomp policies. If you need access to devices use -ice. @sjiveson hmm, I thought it was documented but I cant find the docs now, will have to check and open a docs PR. Here is the typical edit loop using these commands: If you already have a successful build, you can still edit the contents of the .devcontainer folder as required when connected to the container and then select Dev Containers: Rebuild Container in the Command Palette (F1) so the changes take effect. If you started them by hand, VS Code will attach to the service you specified. Web,security,linux-kernel,selinux,seccomp,Security,Linux Kernel,Selinux,Seccomp, FTP Vx32Janus ostia For example, you could install the latest version of the Azure CLI with the following: See the Dev Container Features specification for more details.

Subsequent files override and Here is a simple example devcontainer.json that uses a pre-built TypeScript and Node.js VS Code Development Container image: You can alter your configuration to do things such as: For this example, if you'd like to install the Code Spell Checker extension into your container and automatically forward port 3000, your devcontainer.json would look like: Note: Additional configuration will already be added to the container based on what's in the base image. profile frontend and services without specified profiles. The compose syntax is correct. stdin. Only syscalls on the whitelist are permitted. Confirmed here also, any updates on when this will be resolved? have a docker-compose.yml file in a directory called sandbox/rails. Heres my build command and output: [[emailprotected] docker]$ docker build --tag test -f Dockerfile . Not the answer you're looking for? My environment details in case it's useful; Seeing this also, similar configuration to the @sjiveson. that applies when the spec for a Pod doesn't define a specific seccomp profile. The configuration in the docker-compose.override.yml file is applied over and You can With Compose, we can create a YAML file to define the services and with a Heres my build command and output: [[emailprotected] docker]$ docker build --tag test -f Dockerfile . In this Hire Developers, Free Coding Resources for the Developer. However, if you rebuild the container, you will have to reinstall anything you've installed manually. More information can be found on the Kompose website at http://kompose.io. It uses Berkeley Packet Filter (BPF) rules to filter syscalls and control how they are handled. https://www.kernel.org/doc/Documentation/prctl/seccomp_filter.txt. It will install the Dev Containers extension if necessary, clone the repo into a container volume, and start up the dev container. 6fba0a36935c: Pull complete (this is the default). The reader will learn how to use Docker Compose to manage multi-container applications and how to use Docker Swarm to orchestrate containers. As you make changes, build your dev container to ensure changes take effect. Find centralized, trusted content and collaborate around the technologies you use most. docker-compose not properly passing seccomp profile, Failed to set a seccomp profile on a worker thread Continuously In Logs. How to copy Docker images from one host to another without using a repository. You can also use an interactive bash shell so that your .bashrc is picked up, automatically customizing your shell for your environment: Tools like NVM won't work without using -i to put the shell in interactive mode: The command needs to exit or the container won't start. In this scenario, Docker doesnt actually have enough syscalls to start the container! Webdocker cli ( click here for more info) docker run -d \ --name=firefox \ --security-opt seccomp=unconfined `#optional` \ -e PUID=1000 \ -e PGID=1000 \ -e TZ=Etc/UTC \ -p 3000:3000 \ -v /path/to/config:/config \ --shm-size="1gb" \ --restart unless-stopped \ lscr.io/linuxserver/firefox:latest Parameters process, to a new Pod. Subsequent files Generally it is better to use this feature than to try to modify the seccomp profile, which is complicated and error prone. To monitor the logs of the container in realtime: docker logs -f wireshark. You signed in with another tab or window. Beyond the advantages of having your team use a consistent environment and tool-chain, this also makes it easier for new contributors or team members to be productive quickly. What is the difference between ports and expose in docker-compose? environment variable relates to the -p flag. Open an issue in the GitHub repo if you want to Download that example kind configuration, and save it to a file named kind.yaml: You can set a specific Kubernetes version by setting the node's container image. docker run -it --cap-add mknod --cap-add sys_admin --device /dev/fuse --security-opt seccomp:./my_seccomp_profile.json myimage, ERROR: Cannot start container 4b13ef917b9f3267546e6bb8d8f226460c903e8f12a1d068aff994653ec12d0b: Decoding seccomp profile failed: invalid character '.'

Asking for help, clarification, or responding to other answers. You can supply multiple -f configuration files. How did StorageTek STC 4305 use backing HDDs? First, update the Dev > Containers: Repository Configuration Paths User setting with the local folder you want to use to store your repository container configuration files. The output is similar to: If observing the filesystem of that container, you should see that the The following example command starts an interactive container based off the Alpine image and starts a shell process. You can use Docker Compose binary, docker compose [-f ] [options] [COMMAND] [ARGS], to build and manage multiple services in Docker containers. Use the -f flag to specify the location of a Compose configuration file. You can supply multiple -f configuration files. You may also add a badge or link in your repository so that users can easily open your project in Dev Containers. When stdin is used all paths in the configuration are feature gate enabled # Mounts the project folder to '/workspace'. Here is some information on how Firefox handles seccomp violations. container belonging to that control plane container: You can see that the process is running, but what syscalls did it actually make? line flag, or enable it through the kubelet configuration of the kubelet. You may want to install additional software in your dev container. New Docker jobs added daily. IT won't let me share the logs on a public forum but I'm now beginning to question if the introduction of seccomp warranted more thought than was allotted. Docker supports many security related technologies. From the logs, it appears that CB is trying to make system calls that are killed by seccomp causing CB to crash. You also may not be mapping the local filesystem into the container or exposing ports to other resources like databases you want to access. Kubernetes 1.26 lets you configure the seccomp profile However, this will also prevent you from gaining privileges through setuid binaries. The kernel supports layering filters. You would then reference this path as the. #yyds#DockerDocker. As an example, a badge to open https://github.com/microsoft/vscode-remote-try-java would look like: You can also include an open in dev container link directly: In some cases, you may want to create a configuration for a repository that you do not control or that you would prefer didn't have a configuration included in the repository itself. process, restricting the calls it is able to make from userspace into the The command lets you pick a pre-defined container configuration from a list based on your folder's contents: The predefined container configurations you can pick from come from our first-party and community index, which is part of the Dev Container Specification. default. In order to complete all steps in this tutorial, you must install You should see three profiles listed at the end of the final step: For simplicity, kind can be used to create a single This tutorial assumes you are using Kubernetes v1.26. The remainder of this lab will walk you through a few things that are easy to miss when using seccomp with Docker. Clean up that Pod before moving to the next section: If you take a look at the fine-grained.json profile, you will notice some of the syscalls WebDocker-from-Docker Compose - Includes the Docker CLI and illustrates how you can use it to access your local Docker install from inside a dev container by volume mounting the Steps to reproduce the issue: Use this However, if you want anything running in this service to be available in the container on localhost, or want to forward the service locally, be sure to add this line to the service config: You can see an example of network_mode: service:db in the Node.js and MongoDB example dev container. https://img.shields.io/static/v1?label=Dev%20Containers&message=Open&color=blue&logo=visualstudiocode, https://vscode.dev/redirect?url=vscode://ms-vscode-remote.remote-containers/cloneInVolume?url=https://github.com/microsoft/vscode-remote-try-java, If you already have VS Code and Docker installed, you can click the badge above or [. ) I need to be able fork a process.

This allows for files Status: Downloaded newer image for postgres:latest, Announcing Compose V2 General Availability, COMPOSE_PROJECT_NAME environment variable, Declare default environment variables in file, Use -f to specify name and path of one or more Compose files, Specifying a path to a single Compose file, Use --profile to specify one or more active profiles. Heres an example of how we can list all system calls made by ls: The output above shows the syscalls that will need to be enabled for a container running the ls program to work, in addition to the syscalls required to start a container. Every service definition can be explored, and all running instances are shown for each service. directory name. for the version you are using. 4docker; . relative to the current working directory. Only syscalls on the whitelist are permitted. You can browse the src folder of that repository to see the contents of each Template. When running in Docker 1.10, I need to provide my own seccomp profile to allow mounting. When running in Docker 1.10, I need to provide my own seccomp profile to allow mounting. [COMMAND] [ARGS], to build and manage multiple services in Docker containers. Both have to be enabled simultaneously to use the feature. With the above devcontainer.json, your dev container is functional, and you can connect to and start developing within it. required some effort in analyzing the program. One of these security mechanisms is seccomp, which Docker uses to constrain what system calls containers can run. to your account, Description You can replace the image property in devcontainer.json with dockerfile: When you make changes like installing new software, changes made in the Dockerfile will persist even upon a rebuild of the dev container. #yyds#DockerDocker.

If you've already started the configured containers using the command line, VS Code will attach to the running service you've specified instead. Task Configuration kind documentation about configuration for more details on this. Sign in WebShell access whilst the container is running: docker exec -it wireshark /bin/bash. We host a set of Templates as part of the spec in the devcontainers/templates repository. Docker supports many It is moderately protective while providing wide application compatibility. This tutorial shows some examples that are still beta (since v1.25) and To avoid this problem, you can use the postCreateCommand property in devcontainer.json. Some x86_64 hosts have issues running rdesktop based images even with the latest docker version due to syscalls that are unknown to docker. Run the following strace command from your Docker Host to see a list of the syscalls used by the whoami program. # Runs the service on the same network as the database container, allows "forwardPorts" in devcontainer.json function. In this step you saw how removing particular syscalls from the default.json profile can be a powerful way to start fine tuning the security of your containers. It is possible to write Docker seccomp profiles from scratch. Thank you. @justincormack Fine with that but how do we achieve this?

The remaining steps in this lab will assume that you are running commands from this labs/security/seccomp directory. is used on an x86-64 kernel: although the kernel will normally not Spin up a stand-alone container to isolate your toolchain or speed up setup. successfully. seccomp is essentially a mechanism to restrict system calls that a process may make, so the same way one might block packets coming from some IPs, one can also block process from sending system calls to CPU. Be sure to perform these commands from the command line of your Docker Host and not from inside of the container created in the previous step. container.seccomp.security.alpha.kubernetes.io/[name] (for a single container) Web--security-opt seccomp=unconfined. ptrace is disabled by default and you should avoid enabling it. the native API fields in favor of the annotations. Compose needs special handling here to pass the file from the client side to the API. The only way to use multiple seccomp filters, as of Docker 1.12, is to load additional filters within your program at runtime. This allows you to install new command-line utilities and spin up databases or application services from inside the Linux container. Compose builds the configuration in the order you supply the files. COMPOSE_PROFILES environment variable. looking at the syscall= entry on each line. You may want to copy the contents of your local. Inspect the contents of the seccomp-profiles/deny.json profile. In this step you will use the deny.json seccomp profile included the lab guides repo. before you continue. We'll cover extend a Docker Compose file in the next section. If you dont specify the flag, Compose uses the current For example, the COMPOSE_FILE environment variable docker-compose.yml and a docker-compose.override.yml file. You also learned the order of preference for actions, as well as how to determine the syscalls needed by an individual program. Copyright 2013-2023 Docker Inc. All rights reserved. The functional support for the already deprecated seccomp annotations Has 90% of ice around Antarctica disappeared in less than a decade? As i understand it i need to set the security-opt. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Compose V2 integrates compose functions into the Docker platform, continuing This will be important when referencing the seccomp profiles on the various docker run commands throughout the lab. for this container. Let's say you'd like to add another complex component to your configuration, like a database. for all its containers: The Pod should be showing as having started successfully: Finally, now that you saw that work OK, clean up: To start off, apply the audit.json profile, which will log all syscalls of the Seccomp security profiles for Docker. at least the docker-compose.yml file. Notice that there are no syscalls in the whitelist. You can also edit existing profiles. 4docker; . Use the docker run command to try to start a new container with all capabilities added, apparmor unconfined, and the seccomp-profiles/deny.json seccomp profile applied. javajvm asp.net coreweb However, there are several round-about ways to accomplish this. This profile does not restrict any syscalls, so the Pod should start kernel since version 2.6.12. into the cluster. Once you have added a .devcontainer/devcontainer.json file to your folder, run the Dev Containers: Reopen in Container command (or Dev Containers: Open Folder in Container if you are not yet in a container) from the Command Palette (F1). directory level, Compose combines the two files into a single configuration. system call that takes an argument of type int, the more-significant In this step you will see how applying changes to the default.json profile can be a good way to fine-tune which syscalls are available to containers. cecf11b8ccf3: Pull complete or. configuration in the order you supply the files.
