Here’s an example of using data volumes to share the same data between two CouchDB containers. This could be used for hot upgrades, testing different versions of CouchDB on the same data, etc.
Note that we’re marking /var/lib/couchdb as a data volume.
COUCH1=$(sudo docker run -d -p 5984 -v /var/lib/couchdb shykes/couchdb:2013-05-03)
We’re assuming your Docker host is reachable at localhost. If not, replace localhost with the public IP of your Docker host.
HOST=localhost URL="http://$HOST:$(sudo docker port $COUCH1 5984 | grep -Po 'd+$')/_utils/" echo "Navigate to $URL in your browser, and use the couch interface to add data"
This time, we’re requesting shared access to $COUCH1‘s volumes.
COUCH2=$(sudo docker run -d -p 5984 --volumes-from $COUCH1 shykes/couchdb:2013-05-03)
HOST=localhost URL="http://$HOST:$(sudo docker port $COUCH2 5984 | grep -Po 'd+$')/_utils/" echo "Navigate to $URL in your browser. You should see the same data as in the first database"'!'
Congratulations, you are now running two Couchdb containers, completely isolated from each other except for their data.
