1. Stop existing deployment
|

2. Create a dedicated named docker volume with `docker volume create target-vol`
|

|
|
3. Copy existing contents
|
||
|
|
|
||
|
|
```shell
|
||
|
|
# copy
|
||
|
|
docker run -d --rm --name temp -v target-vol:/mnt alpine tail -f /dev/null
|
||
|
|
docker cp /opt/.../. temp:/mnt
|
||
|
|
|
||
|
|
# once finished
|
||
|
|
docker stop $MIGRATOR_NAME
|
||
|
|
```
|

4. Adapt existing deployment
|
||
|
|
|
||
|
|
```shell
|
||
|
|
# dedicated volumes section
|
||
|
|
volumes:
|
||
|
|
target-vol:
|
||
|
|
external: true
|
||
|
|
|
||
|
|
# change any mount paths
|
||
|
|
volumes:
|
||
|
|
- target-vol:/....
|
||
|
|
```
|
