A push to master here does not just build: it pushes an image, runs the
migrations and restarts the demo container, so the site takes a short outage
each time. The last two merges were markdown only and both paid for it.
Beyond the waste, a deploy can fail for reasons unrelated to the change that
triggered it - a container that will not come up, a database that is briefly
unreachable - and a README edit should not be able to turn the demo red.
Only build.yml is filtered. go.yml still builds on every push and pull request,
so nothing loses its compile check, and the badge keeps reporting the same
workflow it reports today.
Closes#871.
The deploy did docker rm -f then docker run. Nothing ran migrations, so
new code met old tables, and nothing checked the result - a container
that exits immediately left the site down with a green deploy.
Now, in order: pull the image, run the migration with it, and only then
touch what is running. A failed migration stops there, leaving old code
with the old schema, which is at least self-consistent.
The running container is renamed rather than removed, so it can be
started again unchanged if the new one does not become healthy. Healthy
means both an HTTP response and a database connection in the log: the
captcha endpoint answers without touching the database, so it alone
would call a container healthy that cannot reach MySQL.
The path is not a credential, and the file it points at is 600 and owned
by root, so this is not what protects it. But the repository is public
and there is no reason to publish the server's directory layout next to
the deploy that uses it.
DEMO_CONFIG_PATH holds it instead. It has to be set before this merges,
or the deploy stops at the guard - which is the intended failure: better
that than falling back to the sqlite in the image.
The demo ran on the sqlite file baked into the image, so every deploy
reset it and nothing there resembled how anyone actually runs this.
The config is mounted from the host rather than taken from the image.
config/settings.demo.yml ships in a public repository and is copied into
a public image, so the connection string cannot live there; that copy
stays on sqlite, which is what a fresh clone should get.
The deploy refuses to start if the host config is missing, rather than
falling back to the image's sqlite and looking like it worked.
Two merges seconds apart raced. Both runs do docker rm -f then docker
run; the second removed the container the first had just created, and
the first's docker run failed on the name conflict:
Conflict. The container name "/go-admin-api" is already in use
The deploy went red and the demo stayed on the older image, which is the
worse half: a failure that leaves the wrong version running.
Grouping by ref serialises pushes to master while leaving pull request
runs independent, since those carry their own ref.
Replace version tags (@v1/@v2/@v3/@master) with pinned commit SHAs
across all workflow files to satisfy go-admin-team organization
security policy requiring immutable action references.
