# oci-runtime-tool [](https://travis-ci.org/opencontainers/runtime-tools) [](https://goreportcard.com/report/github.com/opencontainers/runtime-tools) oci-runtime-tool is a collection of tools for working with the [OCI runtime specification][runtime-spec]. To build from source code, runtime-tools requires Go 1.19.x or above. ## Table of Contents Additional documentation about how this group operates: - [Code of Conduct][code-of-conduct] - [security][security] ## Generating an OCI runtime spec configuration files [`oci-runtime-tool generate`][generate.1] generates [configuration JSON][config.json] for an [OCI bundle][bundle]. [OCI-compatible runtimes][runtime-spec] like [runC][] expect to read the configuration from `config.json`. $ oci-runtime-tool generate --output config.json $ cat config.json { "ociVersion": "0.5.0", … } ## Validating an OCI bundle [`oci-runtime-tool validate`][validate.1] validates an OCI bundle. The error message will be printed if the OCI bundle failed the validation procedure. $ oci-runtime-tool generate $ oci-runtime-tool validate INFO[0000] Bundle validation succeeded. ## Testing OCI runtimes The runtime validation suite uses [node-tap][], which is packaged for some distributions (for example, it is in [Debian's `node-tap` package][debian-node-tap]). If your distribution does not package node-tap, you can install [npm][] (for example, from [Gentoo's `nodejs` package][gentoo-nodejs]) and use it: $ npm install tap Build the validation executables: $ make runtimetest validation-executables Runtime validation currently [only supports](docs/runtime-compliance-testing.md) the [OCI Runtime Command Line Interface](docs/command-line-interface.md). If we add support for alternative APIs in the future, runtime validation will gain an option to select the desired runtime API. For the command line interface, the `RUNTIME` option selects the runtime command (`funC` in the [OCI Runtime Command Line Interface](docs/command-line-interface.md)). $ sudo make RUNTIME=runc localvalidation RUNTIME=runc tap validation/pidfile.t validation/linux_cgroups_hugetlb.t validation/linux_cgroups_memory.t validation/linux_rootfs_propagation_shared.t validation/kill.t validation/create.t validation/poststart.t validation/linux_cgroups_network.t validation/poststop_fail.t validation/linux_readonly_paths.t validation/prestart_fail.t validation/hooks_stdin.t validation/default.t validation/linux_masked_paths.t validation/poststop.t validation/misc_props.t validation/prestart.t validation/poststart_fail.t validation/mounts.t validation/linux_cgroups_relative_pids.t validation/process_user.t validation/process.t validation/hooks.t validation/process_capabilities_fail.t validation/process_rlimits_fail.t validation/linux_cgroups_relative_cpus.t validation/process_rlimits.t validation/linux_cgroups_relative_blkio.t validation/linux_sysctl.t validation/linux_seccomp.t validation/linux_devices.t validation/start.t validation/linux_cgroups_pids.t validation/process_capabilities.t validation/process_oom_score_adj.t validation/linux_cgroups_relative_hugetlb.t validation/linux_cgroups_cpus.t validation/linux_cgroups_relative_memory.t validation/state.t validation/root_readonly_true.t validation/linux_cgroups_blkio.t validation/linux_rootfs_propagation_unbindable.t validation/delete.t validation/linux_cgroups_relative_network.t validation/hostname.t validation/killsig.t validation/linux_uid_mappings.t validation/pidfile.t .failed to create the container container_linux.go:348: starting container process caused "process_linux.go:402: container init caused \"process_linux.go:367: setting cgroup config for procHooks process caused \\\"failed to write 56892210544640 to hugetlb.1GB.limit_in_bytes: open /sys/fs/cgroup/hugetlb/cgrouptest/hugetlb.1GB.limit_in_bytes: permission denied\\\"\"" exit status 1 validation/pidfile.t .................................. 1/1 315ms validation/linux_cgroups_hugetlb.t .................... 0/1 not ok validation/linux_cgroups_hugetlb.t timeout: 30000 file: validation/linux_cgroups_hugetlb.t command: validation/linux_cgroups_hugetlb.t args: [] stdio: - 0 - pipe - 2 cwd: /…/go/src/github.com/opencontainers/runtime-tools exitCode: 1 validation/linux_cgroups_memory.t ..................... 9/9 validation/linux_rootfs_propagation_shared.t ...... 252/282 not ok shared root propagation exposes "/target348456609/mount892511628/example376408222" Skipped: 29 /dev/null (default device) has unconfigured permissions … total ........................................... 4381/4962 4381 passing (1m) 567 pending 14 failing make: *** [Makefile:44: localvalidation] Error 1 You can also run an individual test executable directly: $ sudo RUNTIME=runc validation/default/default.t TAP version 13 ok 1 - has expected hostname --- { "actual": "mrsdalloway", "expected": "mrsdalloway" } ... … ok 287 # SKIP linux.gidMappings not set 1..287 If you cannot install node-tap, you can probably run the test suite with another [TAP consumer][tap-consumers].
