Summary

Makes the Setup Cloud Test Server label work on this repo. The label is handled by the external matterwick bot, which HEAD-polls a fixed S3 key and installs from it — nothing here produced that artifact, so it never resolved.

  • .github/workflows/ci.yml — a dist job calling the shared reusable workflow plugin-dist-pr.yml@main.
  • Makefileserver-linux and dist-linux, the targets that workflow invokes. This repo had neither.

Follows mattermost-plugin-boards#139, with two deliberate deviations: an if: gate on pull_request (our ci.yml also runs on schedule, master and tags), and verify-target: manifest-check (the build job already runs a full multi-platform make dist).

Ticket

https://mattermost.atlassian.net/browse/MM-70421

Verified in CI

The dist job on this PR uploaded to exactly the key matterwick polls:

upload: dist/com.mattermost.docs-0.0.0+b427c38.tar.gz
     to s3://mattermost-plugin-pr-builds/mattermost-plugin-docs/mattermost-plugin-docs-696b43a.tar.gz

That confirms PLUGIN_DIST_S3_BUCKET is scoped to this repo, and that s3-prefix is load-bearing — unset, the prefix defaults to mattermost-plugins/<repo>, which matterwick does not poll.

Still needed for the label to work end to end

Both outside this repo:

  • Plugin ID mapping — matterwick prefix-strips to docs, but the manifest id is com.mattermost.docs, so the plugin installs and then fails to enable. Fix prepared against gitops-platform's matterwick config secret.
  • matterwick#100 — plugin SpinWicks discarded env vars, so the Docs feature flag couldn't be turned on.

Review Change Stack

📝 Walkthrough

Walkthrough

The Makefile adds Linux AMD64 server and distribution targets. The CI workflow invokes a reusable pull-request distribution workflow, verifies the manifest, and publishes the dist-linux bundle to the Mattermost Docs S3 prefix.

Changes

Linux distribution publishing

Layer / File(s) Summary
Linux build and package
Makefile
The server-linux target builds the Linux AMD64 server binary when a server exists. The dist-linux target applies the manifest and packages the webapp with that binary.
Pull-request distribution workflow
.github/workflows/ci.yml
The pull-request job invokes plugin-dist-pr.yml, uses OIDC and inherited secrets, verifies the manifest, and publishes to the Mattermost Docs S3 prefix.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 696b4

The PR enables PR artifact publishing, but currently passes all available CI secrets to a mutable shared workflow, creating a concrete risk of unintended secret exposure. Restricting the passed secrets and pinning the workflow revision is needed before merge; the Makefile concern is limited to callers that enable parallel builds.

297-300: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick win

Serialize bundle after the build targets.

dist-linux lists apply, server-linux, webapp, and bundle as independent prerequisites. Under make -j, bundle can run before either build completes and can create an incomplete artifact. The current workflow runs make "$DIST_TARGET" without enabling parallel jobs, so this does not affect its default invocation. Serialize these prerequisites if callers can enable parallel Make.

⚠️ Plugin Installation Issue

The test server was created successfully, but there was an issue installing or enabling the plugin automatically:

  • Enable Error: failed to enable plugin via mmctl: failed with status code 409

You can manually install the plugin:

  1. Download the plugin artifact from the link above
  2. Upload it to your test server at razcrbn7hfgx8jpzc7d1uwsm4c
  3. Enable it in System Console > Plugins

Future commits will still attempt to automatically update the plugin.

Plugin test server update attempted, but encountered an issue:

Plugin Version Artifact
docs 696b43a Download

The "Setup Cloud Test Server" label is handled by matterwick, which
HEAD-polls a fixed S3 key for up to 30 minutes and then installs from it:

  <bucket>/mattermost-plugin-docs/mattermost-plugin-docs-<sha7>.tar.gz

Nothing in this repo produced that artifact, so the label could never
resolve. Adds the producer half via the shared reusable workflow, as
mattermost-plugin-boards#139 did, plus the Linux-only build targets it
invokes, which this repo did not have.

s3-prefix is load-bearing rather than cosmetic: left unset the workflow
prefixes with mattermost-plugins/<repo>, which is not the path matterwick
polls. verify-target is manifest-check rather than the default dist because
the build job already runs a full multi-platform make dist on every PR, and
the verify step runs after the artifact is built -- the default would
replace the Linux-only bundle with the multi-platform one before upload.
The run failed to start outright: the called workflow requests id-token:
write, and the workflow-level default of contents: read does not cover it,
so GitHub refused to schedule any job. Matches how boards grants it, and how
delivery and release already do here.
