![]() It is a bit of an advanced exercise, and I’d only really recommend this technique if you need to move volumes from one system to another. If you need to backup the volume itself, usually you can just use another disposable container using the -volumes-from argument to enable tar’ing up the volume contents. By providing a bind-mount of -v /path/to/backups:/backups combined with configuring scheduled backups ( Config->System->Gateway Settings in the Gateway webpage), you can easily have those backups piped back to your host system. The backup method I prefer for most scenarios is utilize a bind-mount into the container as a target for the scheduled gateway backups within Ignition. However, it is usually a good idea to have proper backup strategies in place for your development. The benefits of volumes discussed above are definitely clear. “Image”: “inductiveautomation/ignition:latest”, “test $(./gwcmd.sh -info | grep -c ‘RUNNING’) -ge 1” “PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin”, Use the output from the container listing above to determine which container name should be used for. This will print out a listing of all containers, including stopped ones ![]() I always recommend using named volumes with your containers if you’re doing anything but very temporary work.įirst things first, can you share the output of: I’ll also mention that it is typical that containers are treated as somewhat ephemeral in nature and data persistence for stateful containers (like an Ignition Gateway) is done through the use of volumes. Setting “always restart” shouldn’t cause the container to be removed, but rather restart automatically upon failure. As long as the container is not removed, your data will still be within that container. ![]() When you launch a container, an isolated filesystem is created (based on the image) and changes made live only within the container. Sorry to hear this… There are a few fundamentals to understand when working with Docker.
