# 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 1.7.x or above.
|
|
|
|
## 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`.
|
|
|
|
```console
|
|
$ 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.
|
|
|
|
```console
|
|
$ 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:
|
|
|
|
```console
|
|
$ npm install tap
|
|
```
|
|
|
|
Build the validation executables:
|
|
|
|
```console
|
|
$ make runtimetest validation-executables
|
|
```
|
|
|
|
Runtime validation currently [only supports](docs/runtime-compliance-testing.md) the [OCI Runtime Command Line Interface](doc/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](doc/command-line-interface.md)).
|
|
|
|
```
|
|

You can also run an individual test executable directly:
|
|
|
|
```console
|
|
$ RUNTIME=runc validation/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].
|
|
For example, with [`prove`][prove]:
|
|
|
|
```console
|
|
$ sudo make TAP='prove -Q -j9' RUNTIME=runc VALIDATION_TESTS=validation/pidfile.t localvalidation
|
|
RUNTIME=runc prove -Q -j9 validation/pidfile.t
|
|
All tests successful.
