- # Run OTP releases on older glibc using Docker
- Pleroma OTP releases are built on specific distros and may require a newer `glibc`
- than your host has. A typical failure looks like:
- ```
- ... /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.38' not found ...
- ```
- If you don't want to upgrade your host OS, you can run the existing OTP release
- from `/opt/pleroma` inside an Ubuntu 24.04 container while keeping your existing
- host paths (`/etc/pleroma`, `/var/lib/pleroma`, etc.).
- This folder provides a "shim" container + systemd unit. It is **not** the Pleroma
- Docker image.
- ## What this does
- - Builds a small Ubuntu 24.04 image with runtime libs (including newer `glibc`).
- - Mounts your existing host release at `/opt/pleroma` into the container.
- - Runs as the same UID/GID that owns `/opt/pleroma` on the host (via `gosu`).
- - Optionally runs migrations automatically on container start.
- - Uses `network_mode: host` so your existing config that talks to `localhost`
- keeps working.
- ## Setup (Debian/Ubuntu host)
- 1. Install Docker Engine + the Docker Compose plugin.
- 2. Copy these files to a stable location (example: `/etc/pleroma/container`):
- ```
- mkdir -p /etc/pleroma/container
- cp -a /opt/pleroma/installation/release-to-docker/* /etc/pleroma/container/
- ```
- 3. Build the shim image:
- ```
- cd /etc/pleroma/container
- docker compose build
- ```
- 4. Replace your systemd unit:
- ```
- cp /etc/pleroma/container/pleroma.service /etc/systemd/system/pleroma.service
- systemctl daemon-reload
- systemctl enable --now pleroma
- journalctl -u pleroma -f
- ```
- ## Running `pleroma_ctl`
- Since the host binary may not run on older `glibc`, run admin commands inside the
- container:
- ```
- cd /etc/pleroma/container
- docker compose exec pleroma /opt/pleroma/bin/pleroma_ctl status
- docker compose run --rm --no-deps pleroma /opt/pleroma/bin/pleroma_ctl migrate
- ```
- ## Configuration notes
- - Migrations run automatically by default.
- - Set `PLEROMA_RUN_MIGRATIONS=0` in `docker-compose.yml` to disable.
