Run Docker with the host directory

To run Docker with the host directory:

1. Pull the image:

   docker pull percona/pmm-server:3
   

2. Identify a directory on the host that you want to use to persist PMM data. For example, /home/user/srv.

3. Run the image:

   docker run --detach --restart always \
   --publish 443:8443 \
   --env PMM_WATCHTOWER_HOST=your_watchtower_host \
   --env PMM_WATCHTOWER_TOKEN=your_watchtower_token \
   --volume /home/user/srv:/srv \
   --network=pmm_default \
   --name pmm-server \
   percona/pmm-server:3
   

4. Change the password for the default admin user, replacing your_secure_password with a strong, unique password:

   docker exec -t pmm-server change-admin-password your_secure_password
   

5. Visit https://localhost:443 to see the PMM user interface in a web browser. (If you are accessing the docker host remotely, replace localhost with the IP or server name of the host.)

Migrate from data container to host directory

To migrate your PMM from data container to host directory, run the following command:

docker cp <container-id>:/srv /target/host/directory
