This happens automatically when pre-building using devcontainer.json, which you may read more about in the pre-build section. The reader will learn how to use Docker Compose to manage multi-container applications and how to use Docker Swarm to orchestrate containers. Web --no-sandbox, --disable-setuid-sandbox args . VS Code's container configuration is stored in a devcontainer.json file. in the related Kubernetes Enhancement Proposal (KEP): Once you have a kind configuration in place, create the kind cluster with In order to complete all steps in this tutorial, you must install Compose builds the configuration in the order you supply the files. Copyright 2013-2023 Docker Inc. All rights reserved. Digest: sha256:1364924c753d5ff7e2260cd34dc4ba05ebd40ee8193391220be0f9901d4e1651 relative to the current working directory. 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. WebDocker Compose specific properties Tool-specific properties While most properties apply to any devcontainer.json supporting tool or service, a few are specific to certain tools. Your comment suggests there was little point in implementing seccomp in the first place. required some effort in analyzing the program. Your use of Play With Docker is subject to the Docker Terms of Service which can be accessed. enable the use of RuntimeDefault as the default seccomp profile for all workloads necessary syscalls and specified that an error should occur if one outside of Change into the labs/security/seccomp directory. At the end of using Dev Containers: Add Dev Container Configuration Files, you'll be shown the list of available features, which are tools and languages you can easily drop into your dev container. Since 1.12, if you add or remove capabilities the relevant system calls also get added or removed from the seccomp profile automatically. Heres my build command and output: [[emailprotected] docker]$ docker build --tag test -f Dockerfile . Its a very good starting point for writing seccomp policies. If you supply a -p flag, you can 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. syscalls. When restarted, CB tries to replay the actions from before the crash causing it to crash again. Have a question about this project? 50cf91dc1db8: Pull complete For example, this happens if the i386 ABI Kubernetes cluster, how to apply them to a Pod, and how you can begin to craft The above command sends the JSON file from the client to the daemon where it is compiled into a BPF program using a thin Go wrapper around libseccomp. is going to be removed with a future release of Kubernetes. Start another new container with the default.json profile and run the same chmod 777 / -v. The command succeeds this time because the default.json profile has the chmod(), fchmod(), and chmodat syscalls included in its whitelist. You can use this script to test for seccomp escapes through ptrace. Some x86_64 hosts have issues running rdesktop based images even with the latest docker version due to syscalls that are unknown to docker. The text was updated successfully, but these errors were encountered: I'm suffering from the same issue and getting the same error output. only the privileges they need. Configure IntelliSense for cross-compiling, extend your existing Docker Compose setup, attach to an already running container instead, Extend your existing Docker Compose configuration, work with multiple Docker Compose-defined services, Adding a non-root user to your dev container, Node.js and MongoDB example dev container, https://github.com/microsoft/vscode-remote-try-java. See also the COMPOSE_PROJECT_NAME environment variable. WebDocker compose does not work with a seccomp file AND replicas toghether. Chromes DSL for generating seccomp BPF programs. others that use only generally available seccomp functionality. Every service definition can be explored, and all running instances are shown for each service. running the Compose Rails sample, and Thank you for your contributions. However, on Linux you may need to set up and specify a non-root user when using a bind mount or any files you create will be root. "mcr.microsoft.com/devcontainers/typescript-node:0-18", "mcr.microsoft.com/devcontainers/typescript-node", "ghcr.io/devcontainers/features/azure-cli:1", mcr.microsoft.com/devcontainers/javascript-node:0-18, apt-get update && export DEBIAN_FRONTEND=noninteractive \, "the-name-of-the-service-you-want-to-work-with-in-vscode", "/default/workspace/path/in/container/to/open". Translate a Docker Compose File to Kubernetes Resources What's Kompose? The following example command starts an interactive container based off the Alpine image and starts a shell process. This gives you the confidence the behavior you see in the following steps is solely due to seccomp changes. docker save tar docker load imagedata.tar layerdocker load tar recommends that you enable this feature gate on a subset of your nodes and then You can find more detailed information about a possible upgrade and downgrade strategy have a docker-compose.yml file in a directory called sandbox/rails. shophq official site. # Overrides default command so things don't shut down after the process ends. You may want to copy the contents of your local. 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. You can also reuse an existing Dockerfile: Now that you have a devcontainer.json and Dockerfile, let's see the general process for editing container configuration files. Seccomp stands for secure computing mode and has been a feature of the Linux kernel since version 2.6.12. It will be closed if no further activity occurs. dockeryamldocker -v yamldocker /data/nginx/conf/nginx.conf:/etc/nginx/nginx.conf Sign in You'll be prompted to pick a pre-defined container configuration from our first-party and community index in a filterable list sorted based on your folder's contents. I'm trying to run an s3fs-fuse docker image, which requires the ability to mount. at least the docker-compose.yml file. You also learned the order of preference for actions, as well as how to determine the syscalls needed by an individual program. issue happens only occasionally): My analysis: You also may not be mapping the local filesystem into the container or exposing ports to other resources like databases you want to access. Compose V2 integrates compose functions into the Docker platform, continuing You've now configured a dev container in Visual Studio Code. For Docker Compose, run your container with: security_opt:-seccomp=unconfined. It can be used to sandbox the privileges of a As seen in the previous example, the http-echo process requires quite a few docker network security and routing - By default, docker creates a virtual ethernet card for each container. From inside of a Docker container, how do I connect to the localhost of the machine? Only syscalls on the whitelist are permitted. New Docker jobs added daily. The simplest and easiest to understand definition of seccomp is probably a "firewall for syscalls". The dev container configuration is either located under .devcontainer/devcontainer.json or stored as a .devcontainer.json file (note the dot-prefix) in the root of your project. Clicking these links will cause VS Code to automatically install the Dev Containers extension if needed, clone the source code into a container volume, and spin up a dev container for use. The remaining steps in this lab will assume that you are running commands from this labs/security/seccomp directory. So what *is* the Latin word for chocolate? You can add other services to your docker-compose.yml file as described in Docker's documentation. When running in Docker 1.10, I need to provide my own seccomp profile to allow mounting. Compose traverses the working directory and its parent directories looking for a For example, consider this additional .devcontainer/docker-compose.extend.yml file: This same file can provide additional settings, such as port mappings, as needed. This bug is still present. Does Cosmic Background radiation transmit heat? Check both profiles for the presence of the chmod(), fchmod(), and chmodat() syscalls. enable the feature, either run the kubelet with the --seccomp-default command Seccomp, and user namespaces. follows: docker compose -f ~/sandbox/rails/docker-compose.yml pull db. This tutorial shows some examples that are still beta (since v1.25) and This was not ideal. As a beta feature, you can configure Kubernetes to use the profile that the Also, can we ever expect real compose support rather than a workaround? You should see three profiles listed at the end of the final step: For simplicity, kind can be used to create a single You can begin to understand the syscalls required by the http-echo process by CB 4.5 crashes constantly after upgrading to Docker 2.13 and Compose 1.8. Caveats It seems most ARM Synology don't support seccomp, so the Docker container has unfettered access to your system (even more so than with a regular docker). Set secomp to unconfined in docker-compose. To use seccomp profile defaulting, you must run the kubelet with the SeccompDefault Both containers start succesfully. You can adopt these defaults for your workload by setting the seccomp in /opt/collabora-mydomain: docker-compose.yml Copy to clipboard Download version: '3' services: code: image: collabora/code:latest restart: always environment: - password=${COLLABORA_PASSWORD} - Leverage your professional network, and get hired. Most container images are based on Debian or Ubuntu, where the apt or apt-get command is used to install new packages. When you use multiple Compose files, all paths in the files are relative to the This error gist which states that the content of the seccomp.json file is used as the filename, Describe the results you expected: You also used the strace program to list the syscalls made by a particular run of the whoami program. with docker compose --profile frontend --profile debug up You would then reference this path as the. The rule only matches if all args match. One such way is to use SCMP_ACT_TRAP and write your code to handle SIGSYS and report the errors in a useful way. ability to do anything meaningful. Subsequent files As part of the demo you will add all capabilities and effectively disable apparmor so that you know that only your seccomp profile is preventing the syscalls. When checking values from args against a blacklist, keep in mind that How can I think of counterexamples of abstract mathematical objects? use a command like docker compose pull to get the fields override the previous file. More information can be found on the Kompose website at http://kompose.io. It indicates, "Click to perform a search". Older versions of seccomp have a performance problem that can slow down operations. defined by the container runtime, instead of using the Unconfined (seccomp disabled) mode. See: A good way to avoid this issue in Docker 1.12+ can be to use the --security-opt no-new-privileges flag when starting your container. command line. docker compose options, including the -f and -p flags. gate is enabled by Use the -f flag to specify the location of a Compose configuration file. Note: If you are using Docker Desktop for Windows or MacOS, please check our FAQ. 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. In this step you will use the deny.json seccomp profile included the lab guides repo. In general you should avoid using the --privileged flag as it does too many things. Open up a new terminal window and use tail to monitor for log entries that By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Check what port the Service has been assigned on the node. You may want to install additional software in your dev container. suggest an improvement. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. worker: Most container runtimes provide a sane set of default syscalls that are allowed Docker seccomp profiles operate using a whitelist approach that specifies allowed syscalls. node cluster with the seccomp profiles loaded. and download them into a directory named profiles/ so that they can be loaded It will install the Dev Containers extension if necessary, clone the repo into a container volume, and start up the dev container. 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. You could run the following commands in the integrated terminal in VS Code: You may also use the "features" property in the devcontainer.json to install tools and languages from a pre-defined set of Features or even your own. Task Configuration You can easily share a customized Dev Container Template for your project by adding devcontainer.json files to source control. 338a6c4894dc: Pull complete In this document, we'll go through the steps for creating a development (dev) container in VS Code: After any of the steps above, you'll have a fully functioning dev container, and you can either continue to the next step of this tutorial to add more features, or stop and begin working in the dev environment you currently have. type in the security context of a pod or container to RuntimeDefault. However, there are several round-about ways to accomplish this. The kernel supports layering filters. Fortunately, Dev Containers supports Docker Compose managed multi-container configurations. Tip: Want to use a remote Docker host? for this container. Let's say you want to install Git. You can substitute whoami for any other program. mention calls from http-echo: Next, expose the Pod with a NodePort Service: Check what port the Service has been assigned on the node: Use curl to access that endpoint from inside the kind control plane container: You should see no output in the syslog. If you dont specify the flag, Compose uses the current 17,697. Use docker exec to run a command in the Pod: You have verified that these seccomp profiles are available to the kubelet In this step you will see how to force a new container to run without a seccomp profile. Is there a proper earth ground point in this switch box? I've tried running with unconfined profile, cap_sys_admin, nothing worked. Ideally, the container will run successfully and you will see no messages What are examples of software that may be seriously affected by a time jump? While this file is in .devcontainer. WebDocker Compose is a tool that was developed to help define and share multi-container applications. half of the argument register is ignored by the system call, but You can use Docker Compose binary, docker compose [-f ] [options] But the security_opt will be applied to the new instance of the container and thus is not available at build time like you are trying to do with add to their predecessors. before you continue. Install additional tools such as Git in the container. Not the answer you're looking for? process, restricting the calls it is able to make from userspace into the Once the configuration runs, a new section called Compose will be available in the Services Tool Window under the Docker node. mastiff fucks wife orgasm Each configuration has a project name. If both files are present on the same Indeed, quite the dumping ground. 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. See moby/moby#19060 for where this was added in engine. An image is like a mini-disk drive with various tools and an operating system pre-installed. With the above devcontainer.json, your dev container is functional, and you can connect to and start developing within it. docker inspect -f ' { { index .Config.Labels "build_version" }}' Step 3 - Run a container with no seccomp profile, https://github.com/docker/engine-api/blob/c15549e10366236b069e50ef26562fb24f5911d4/types/seccomp.go, https://github.com/opencontainers/runtime-spec/blob/6be516e2237a6dd377408e455ac8b41faf48bdf6/specs-go/config.go#L502, https://github.com/docker/docker/issues/22252, https://github.com/opencontainers/runc/pull/789, https://github.com/docker/docker/issues/21984, http://man7.org/linux/man-pages/man2/seccomp.2.html, http://man7.org/conf/lpc2015/limiting_kernel_attack_surface_with_seccomp-LPC_2015-Kerrisk.pdf, https://cs.chromium.org/chromium/src/sandbox/linux/bpf_dsl/bpf_dsl.h?sq=package:chromium&dr=CSs, Invoke a ptracer to make a decision or set, A Linux-based Docker Host with seccomp enabled, Docker 1.10 or higher (preferably 1.12 or higher), To prove that we are not running with the default seccomp profile, try running a, SCMP_CMP_MASKED_EQ - masked equal: true if. 81ef0e73c953: Pull complete You will complete the following steps as part of this lab. Unless you specify a different profile, Docker will apply the default seccomp profile to all new containers. Use a -f with - (dash) as the filename to read the configuration from 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. How to copy Docker images from one host to another without using a repository. If you are running this on another environment, you will need: The following commands show you how to check if seccomp is enabled in your systems kernel: If the above output does not return a line with seccomp then your system does not have seccomp enabled in its kernel. Secure computing mode ( seccomp) is a Linux kernel feature. # Runs the service on the same network as the database container, allows "forwardPorts" in devcontainer.json function. 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 [. ) Version 1.76 is now available! To have VS Code run as a different user, add this to devcontainer.json: If you want all processes to run as a different user, add this to the appropriate service in your Docker Compose file: If you aren't creating a custom Dockerfile for development, you may want to install additional developer tools such as curl inside the service's container. relates to the -f flag, and COMPOSE_PROJECT_NAME uname -r 1.2. You must supply Stack Overflow. 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. or not. When you run a container it gets the default seccomp profile unless you override this by passing the --security-opt flag to the docker run command. Thank you. WebDelete the container: docker rm filezilla. for the version you are using. For more information, see the Evolution of Compose. If you started them by hand, VS Code will attach to the service you specified. Docker is a platform that allows developers to rapidly build, deploy and run applications via the use of The remainder of this lab will walk you through a few things that are easy to miss when using seccomp with Docker. syscalls. The text was updated successfully, but these errors were encountered: This issue has been automatically marked as stale because it has not had recent activity. [COMMAND] [ARGS], to build and manage multiple services in Docker containers. From the VS Code UI, you may select one of the following Templates as a starting point for Docker Compose: After you make your selection, VS Code will add the appropriate .devcontainer/devcontainer.json (or .devcontainer.json) file to the folder. However, you still need to enable this defaulting for each node where using docker exec to run crictl inspect for the container on the kind "defaultAction": "SCMP_ACT_ERRNO". Identifying the privileges required for your workloads can be difficult. I think putting seccomp:unconfined should work, but you cannot use a specific file until this is fixed. From the logs, it appears that CB is trying to make system calls that are killed by seccomp causing CB to crash.
