# buildpack-deps docker images
|
|
|
|
|
|
|
|
|
|
The `buildpack-deps` docker images are used to compile and test solidity within our CI.
|
|
|
|
|
|
|
|
|
|
## GitHub Workflow
|
|
|
|
|
|
|
|
|
|
The creation of the images are triggered by a single workflow, defined in `.github/workflows/buildpack-deps.yml`.
|
|
|
|
|
For each resulting `buildpack-deps` docker image a strategy is defined in the workflow file - the image variant.
|
|
|
|
|
The workflow gets triggered, if any Dockerfile defined in `scripts/docker/buildpack-deps/Dockerfile.*` were changed
|
|
|
|
|
within the PR.
|
|
|
|
|
|
|
|
|
|
### Versioning
|
|
|
|
|
|
|
|
|
|
The version of the docker images can be defined within the Dockerfile with `LABEL version`. A new docker image
|
|
|
|
|
will only be created and pushed, if the new version is incremented by `1` compared with the version of the Dockerfile
|
|
|
|
|
located in `develop`.
|
|
|
|
|
|
|
|
|
|
### Build, Test & Push
|
|
|
|
|
|
|
|
|
|
Note that the whole workflow - including all defined strategies (image variants) - will be triggered,
|
2022-08-13 02:41:04 +00:00
|
|
|
even if only a single Dockerfile was changed. The full workflow will only get executed, if the corresponding
|
2020-06-23 17:17:15 +00:00
|
|
|
Dockerfile was changed. The execution of workflows of unchanged Dockerfiles will not continue and just return success.
|
|
|
|
|
See `scripts/ci/docker_upgrade.sh`.
|
|
|
|
|
|
|
|
|
|
If the version check was successful, the docker image will be built using the Dockerfile located in
|
|
|
|
|
`scripts/docker/buildpack-deps/Dockerfile.*`.
|
|
|
|
|
|
2022-08-13 02:41:04 +00:00
|
|
|
The resulting docker image will be tested by executing the corresponding `scripts/ci/buildpack-deps_test_*` scripts.
|
|
|
|
|
Some of these scripts are symlinked to `scripts/ci/build.sh`, except the following two:
|
|
|
|
|
* `buildpack-deps-ubuntu1604.clang.ossfuzz` => `scripts/ci/build_ossfuzz.sh`
|
|
|
|
|
* `buildpack-deps_test_emscripten.sh` => `scripts/ci/build_emscripten.sh`
|
|
|
|
|
|
2020-06-23 17:17:15 +00:00
|
|
|
These scripts `scripts/ci/build.sh` and `scripts/ci/build_ossfuzz.sh` are also used by CircleCI, see `.circleci/config.yml`.
|
|
|
|
|
|
|
|
|
|
If the tests passed successfully, the docker image will get tagged by the version defined within the corresponding `Dockerfile`.
|
|
|
|
|
Finally, a comment will be added to the PR that contains the full repository, version and repository digest
|
2022-08-13 02:41:04 +00:00
|
|
|
of the freshly created docker image.
|
2022-08-25 14:33:56 +00:00
|
|
|
|
|
|
|
|
The files `.circleci/config.yml` and `scripts/build_emscripten.sh` need to be updated with the new hash posted in the comment.
