- 1.2.2 release notes: https://github.com/opencontainers/runc/releases/tag/v1.2.2 - 1.2.1 release notes: https://github.com/opencontainers/runc/releases/tag/v1.2.1 - 1.2.0 release notes: https://github.com/opencontainers/runc/releases/tag/v1.2.0 Breaking changes and deprecations are included below; Breaking changes: Several aspects of how mount options work has been adjusted in a way that could theoretically break users that have very strange mount option strings. This was necessary to fix glaring issues in how mount options were being treated. The key changes are: - Mount options on bind-mounts that clear a mount flag are now always applied. Previously, if a user requested a bind-mount with only clearing options (such as rw,exec,dev) the options would be ignored and the original bind-mount options would be set. Unfortunately this also means that container configurations which specified only clearing mount options will now actually get what they asked for, which could break existing containers (though it seems unlikely that a user who requested a specific mount option would consider it "broken" to get the mount options they asked foruser who requested a specific mount option would consider it "broken" to get the mount options they asked for). This also allows us to silently add locked mount flags the user did not explicitly request to be cleared in rootless mode, allowing for easier use of bind-mounts for rootless containers. - Container configurations using bind-mounts with superblock mount flags (i.e. filesystem-specific mount flags, referred to as "data" in mount(2), as opposed to VFS generic mount flags like MS_NODEV) will now return an error. This is because superblock mount flags will also affect the host mount (as the superblock is shared when bind-mounting), which is obviously not acceptable. Previously, these flags were silently ignored so this change simply tells users that runc cannot fulfil their request rather than just ignoring it. Deprecated - runc option --criu is now ignored (with a warning), and the option will be removed entirely in a future release. Users who need a non-standard criu binary should rely on the standard way of looking up binaries in $PATH. - runc kill option -a is now deprecated. Previously, it had to be specified to kill a container (with SIGKILL) which does not have its own private PID namespace (so that runc would send SIGKILL to all processes). Now, this is done automatically. - github.com/opencontainers/runc/libcontainer/user is now deprecated, please use github.com/moby/sys/user instead. It will be removed in a future release.

About
This directory contains a collection of scripts used to build and manage this repository. If there are any issues regarding the intention of a particular script (or even part of a certain script), please reach out to us. It may help us either refine our current scripts, or add on new ones that are appropriate for a given use case.
DinD (dind.sh)
DinD is a wrapper script which allows Docker to be run inside a Docker container. DinD requires the container to be run with privileged mode enabled.
Generate Authors (generate-authors.sh)
Generates AUTHORS; a file with all the names and corresponding emails of individual contributors. AUTHORS can be found in the home directory of this repository.
Make
There are two make files, each with different extensions. Neither are supposed
to be called directly; only invoke make. Both scripts run inside a Docker
container.
make.ps1
- The Windows native build script that uses PowerShell semantics; it is limited
unlike
hack\make.shsince it does not provide support for the full set of operations provided by the Linux counterpart,make.sh. However,make.ps1does provide support for local Windows development and Windows to Windows CI. More information is found withinmake.ps1by the author, @jhowardmsft
make.sh
- Referenced via
make testwhen running tests on a local machine, or directly referenced when running tests inside a Docker development container. - When running on a local machine,
make testto run all tests found intest,test-unit,test-integration, andtest-docker-pyon your local machine. The default timeout is set inmake.shto 60 minutes (${TIMEOUT:=60m}), since it currently takes up to an hour to run all of the tests. - When running inside a Docker development container,
hack/make.shdoes not have a single target that runs all the tests. You need to provide a single command line with multiple targets that performs the same thing. An example referenced from Run targets inside a development container:root@5f8630b873fe:/go/src/github.com/moby/moby# hack/make.sh dynbinary binary test-unit test-integration test-docker-py - For more information related to testing outside the scope of this README, refer to Run tests and test documentation
Vendor (vendor.sh)
A shell script that is a wrapper around go mod vendor.
