OpenPostInstall on Coolify
Deploy OpenPost on Coolify with the Git-repository Docker Compose build pack.
Deploy OpenPost from Git with Coolify's Docker Compose build pack and the supplied deploy/coolify/docker-compose.yml. The image supports x86_64 servers. Other architectures need amd64 emulation.
What you need
- A Coolify project and environment.
- A domain pointed at the server (for example
post.example.com). - Two independent secrets generated with
openssl rand -base64 32.
Add these values under Configuration → Environment Variables with Runtime scope:
| Variable | What to enter |
|---|---|
OPENPOST_APP_URL | https://post.example.com |
OPENPOST_PUBLIC_URL | https://post.example.com |
OPENPOST_MEDIA_URL | https://post.example.com/media |
OPENPOST_JWT_SECRET | Fresh output of openssl rand -base64 32 |
OPENPOST_ENCRYPTION_KEY | A second, independent openssl rand -base64 32 value |
OPENPOST_DISABLE_REGISTRATIONS | true once the first administrator exists (optional, defaults to false) |
Keep both secrets stable across restarts and restores. Do not commit them to the repository.
Deploy
- Create a Public Repository resource with
https://github.com/getopenpost/openpost. Use a deploy key or GitHub App for a private fork. - Set the build pack to Docker Compose, with Base Directory
/and Docker Compose Locationdeploy/coolify/docker-compose.yml. - Enter the environment variables above.
- Set the
openpostservice domain tohttps://post.example.com:8080. The port suffix tells Coolify where to route traffic; visitors still use normal HTTPS. - Deploy, then verify:
curl https://post.example.com/api/v1/readyExpect "status":"ready" and "database":"ok". If it fails, inspect the deployment logs and confirm that all three URL variables use the same public origin.
Open the app and create the first account. It becomes the instance administrator. The deployment stores SQLite and media in the openpost_data volume.
Updates and backups
Pin image: to a release tag, then redeploy that commit to upgrade. Before changing it, back up the openpost_data volume and environment values, and record the current image tag. Coolify stores the volume on its host, not inside the container.
Keep backups private and off the server. A rollback may require the backup made for the previous version. Follow the maintenance checklist.
