20.8. kb-00007: Example Docker Volume Usage¶
20.8.1. Knowledge Base Article: kb-00007¶
Digital Rebar Provision writes content in the Docker Container to the
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 usage scenario.
Managing Docker volumes with
dr-provision service to back the data stores.
- Create a volume for the container
export VOL="drp-data" # create a Docker volume docker volume create $VOL
- 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:
# now run DRP with our volume mapped to /provision/drp-data: docker run --volume $VOL:/provision/drp-data --name drp -itd --net host digitalrebar/provision:stable
- Verify that DRP extracted the assets on the host in the mounted volume location:
# when DRP starts up, it extracts and builds the default assets # in the writable backing store (directory structure): ls $(docker volume inspect drp-data | jq -r '..Mountpoint') # outputs: # digitalrebar job-logs plugins replace saas-content secrets tftpboot ux
