Upgrade your Docker Funkwhale installation

If you installed Funkwhale following the Docker guide, follow these steps to upgrade.

Upgrade Funkwhale

SSH into your server
Log in as your funkwhale user.
```
su funkwhale
```
Navigate to your Funkwhale directory.
```
cd /srv/funkwhale
```
Export the Funkwhale version you want to update to. You’ll use this in the rest of the commands in this guide.
```
export FUNKWHALE_VERSION=1.4.0
```
Change the version number in your .env file. Update this to the same version number you exported in step 4.
```
nano .env
```
Log in as su to load the configuration from your .env file.
```
sudo su
source .env
```
Pull the updated containers.
```
docker compose pull
```

Apply the database migrations.

docker compose run --rm api funkwhale-manage migrate

Relaunch your containers.
```
docker compose up -d
```
Exit the root shell.

exit

That’s it! You’ve updated your Funkwhale pod. You should now see the new version running in your web browser.

Update your reverse proxy configuration

To ensure your reverse proxy is up-to-date with changes, you should regenerate your Nginx configuration with each upgrade. To do this:

Log in to a root shell to make changes to the config files
```
$ sudo su
```

Download the new Nginx templates from Funkwhale

# curl -L -o /etc/nginx/funkwhale_proxy.conf "https://dev.funkwhale.audio/funkwhale/funkwhale/raw/$FUNKWHALE_VERSION/deploy/funkwhale_proxy.conf"
# curl -L -o /etc/nginx/sites-available/funkwhale.template "https://dev.funkwhale.audio/funkwhale/funkwhale/raw/$FUNKWHALE_VERSION/deploy/docker.proxy.template"

Update the Nginx configuration with details from your .env file

# set -a && source /srv/funkwhale/config/.env && set +a
envsubst "`env | awk -F = '{printf \" $%s\", $$1}'`" \
   < /etc/nginx/sites-available/funkwhale.template \
   > /etc/nginx/sites-available/funkwhale.conf

Check the configuration file to make sure the template values have been updated properly
```
# grep '${' /etc/nginx/sites-available/funkwhale.conf
```

Once you’ve updated your configuration, reload Nginx.

# systemctl reload nginx

Upgrade the Postgres container

Funkwhale depends on Postgres for its database container. To upgrade Postgres, you need to export your database and import it into a new container to update the schema.

To update your Postgres container, follow these steps:

Stop all Funkwhale services
```
# docker compose down
```
Create a backup of your Funkwhale database. We will import this into the new postgres container later.
```
# docker compose run --rm postgres pg_dump -U postgres postgres > db_dump.sql
```
Move the data/postgres directory to another location to back it up
```
$ mv data/postgres data/postgres.bak
```
Create a new data/postgres directory to house your data
```
$ mkdir data/postgres
```
Edit the docker-compose.yml file in an editor of your choice.
```
$ nano docker-compose.yml
```

Update the version number in the image section of the postgres service to the major version you want to use. In this example, Postgres version 15 is used.

version: "3"

services:
postgres:
  restart: unless-stopped
  env_file: .env
  environment:
    - "POSTGRES_HOST_AUTH_METHOD=trust"
  image: postgres:15-alpine
  volumes:
    - ./data/postgres:/var/lib/postgresql/data

Save the file and close your editor

Once you’ve updated your Postgres containers, you need to migrate your database. To do this:

Start up your new database container.
```
# docker compose up -d postgres
```

Import your database dump into the new container.

# cat db_dump.sql | docker compose exec -T postgres psql -U postgres

Run the database migrations.

# docker compose run --rm api funkwhale-manage migrate

Start your Funkwhale instance

Once you have imported your database and run migrations, you can start all containers.

# docker compose up -d
