oci-runtime-tool

oci-runtime-tool is a collection of tools for working with the OCI runtime specification. To build from source code, runtime-tools requires Go 1.7.x or above.

Generating an OCI runtime spec configuration files

oci-runtime-tool generate generates configuration JSON for an OCI bundle. OCI-compatible runtimes 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 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
