Updating PMM Server Using Docker
To check the version of PMM Server, run docker ps on the host.
Run the following commands as root or by using the sudo command
$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 480696cd4187 percona/pmm-server:1.4.0 "/opt/entrypoint.sh" 4 weeks ago Up About an hour 192.168.100.1:80->80/tcp, 443/tcp pmm-server
The version number is visible in the Image column. For a Docker
container created from the image tagged
latest, the Image column
latest and not the specific version number of PMM Server.
The information about the currently installed version of PMM Server is
available from the
/srv/update/main.yml file. You may extract the version
number by using the docker exec command:
$ docker exec -it pmm-server head -1 /srv/update/main.yml # v1.5.3
To check if there exists a newer version of PMM Server, visit percona/pmm-server.
You need to create a backup version of the current
pmm-server container if
the update procedure does not complete successfully or if you decide not to
upgrade your PMM Server after trying the new version.
The docker stop command stops the currently running
$ docker stop pmm-server
The following command simply renames the current
pmm-server container to
avoid name conflicts during the update procedure:
$ docker rename pmm-server pmm-server-backup
Docker images for all versions of PMM are available from percona/pmm-server Docker repository.
When pulling a newer Docker image, you may either use a specific version
number or the
latest image which always matches the highest version
This example shows how to pull a specific version:
$ docker pull percona/pmm-server:1.5.0
This example shows how to pull the
$ docker pull percona/pmm-server:latest
After you have pulled a new version of PMM from the Docker repository, you can
use docker run to create a
pmm-server container using the new image.
$ docker run -d \ -p 80:80 \ --volumes-from pmm-data \ --name pmm-server \ --restart always \ percona/pmm-server:latest
pmm-server container must be stopped before attempting docker run.
The docker run command refers to the pulled image as the last parameter. If
you used a specific version number when running docker pull (see
Pulling the PMM Server Docker Image) replace
Note that this command also refers to
pmm-data as the value of
--volumes-from option. This way, your new version will continue to use the
Do not remove the
pmm-data container when updating,
if you want to keep all collected data.
Check if the new container is running using docker ps.
$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 480696cd4187 percona/pmm-server:1.5.0 "/opt/entrypoint.sh" 4 minutes ago Up 4 minutes 192.168.100.1:80->80/tcp, 443/tcp pmm-server
Then, make sure that the PMM version has been updated (see PMM Version) by checking the PMM Server web interface.
After you have tried the features of the new version, you may decide to continupe using it. The backup container that you have stored (Creating a backup version of the current pmm-server Docker container) is no longer needed in this case.
To remove this backup container, you need the docker rm command:
$ docker rm pmm-server-backup
As the parameter to docker rm, supply the tag name of your backup container.
Restoring the previous version
If, for whatever reason, you decide to keep using the old version, you just need
to stop and remove the new
$ docker stop pmm-server && docker rm pmm-server
Now, rename the
(see Creating a backup version of the current pmm-server Docker container) and start it.
$ docker start pmm-server
Do not use the docker run command to start the container. The docker run command creates and then runs a new container.
To start a new container use the docker start command.
