"defaultAction": "SCMP_ACT_ERRNO". Successfully merging a pull request may close this issue. By default, the project name is simply the name of the directory that the docker-compose.yml was located in. If you twirl down the app, you will see the two containers we defined in the compose file. The names are also a little more descriptive, as they follow the pattern of -. There is no easy way to use seccomp in a mode that reports errors without crashing the program. In this step you removed capabilities and apparmor from interfering, and started a new container with a seccomp profile that had no syscalls in its whitelist. 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. The most important actions for Docker users are SCMP_ACT_ERRNO and SCMP_ACT_ALLOW. visible in the seccomp data. 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. There is also a postStartCommand that executes every time the container starts. You can also see this information by running docker compose --help from the Make and persist changes to the dev container, such as installation of new software, through use of a Dockerfile. upgrade docker, or expect all newer, up-to-date base images to fail in the future.
