Example Docker Volume Usage
Digital Rebar Provision writes content in the Docker Container to the
/provision/drp-data directory by default. Most DRP Endpoint
provisioning systems will want to have persistent data across the
container runtimes. For this, you need to add a Docker Volume. The below
example shows you how to use the local Docker host as the backing store
for the volume. You can also use any of the container based networked
storage solutions to back your volume in.
install.sh script has options to create/start DRP as a container
service. It also will created a backing data store volume by default.
This information is for operators who wish to customize their Volume
Managing Docker volumes with
dr-provision service to back the data
Create a volume for the container
Let's verify that the volume is currently empty
docker volume inspect $VOL | jq '..Mountpoint' # outputs: # "/docker/volumes/drp-data/_data" # show the contents of the current (empty) volume ls -la $(docker volume inspect $VOL | jq -r '..Mountpoint') # total 0 # drwxr-xr-x. 2 root root 40 Aug 21 00:41 . # dr-xr-x===. 1 root root 180 Aug 21 00:41 ..
Launch DRP, using our newly created volume:
Verify that DRP extracted the assets on the host in the mounted volume location:
