Deployments, logs and rollbacks
Follow a deploy live, read your app's logs, redeploy, and roll back to an earlier version.
Follow a deploy
Every deploy has its own page, with its steps and the full build log, live. Open it from the project's Overview or the Deployments tab.
When a deploy fails, the page says which step failed and why. For an app that built but didn't start, it shows the app's last output and the fixes we can apply for you.
Deployments history
The Deployments tab lists every deploy: when, which commit, how long it took, and whether it went live.
- Redeploy builds and starts the current code again: useful after changing variables.
- Roll back puts an earlier version back online. When we still keep its image, there's no rebuild, so it takes seconds.
Logs
The Logs tab shows your app's own output (what it prints to stdout and stderr), live.
App logs are on paid plans
On Free, you keep every deploy's build log and the output shown when a start fails. Live app logs come with Hobby and up.
From the terminal:
dock logs --follow # stream your app's output
dock logs --build # the latest build's logRate a deploy
When a deploy goes live, you can rate how it went in one click. We read every rating to find what to make easier.
