- Remove extraneous '-' in sudo note. - Correct space formatting (minor). - Simplify instructions for install EPEL and install with yum directly. - Add `nodejs` to yum install list explicitly to match the comments -- more transparent for new users who might not be clear `npm` package also installs `nodejs`. - Remove '--noprealloc` from MongoDB example as the option has been depcated since Mongo 2.6 and is now the default behaviour.

Dockerizing a CouchDB service
Note
: If you don't like sudo then see Giving non-root access
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.
Create first database
Note that we're marking /var/lib/couchdb
as a data volume.
$ COUCH1=$(docker run -d -p 5984 -v /var/lib/couchdb shykes/couchdb:2013-05-03)
Add data to the first database
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://$HOST:$(docker port $COUCH1 5984 | grep -o '[1-9][0-9]*$')/_utils/"
$ echo "Navigate to $URL in your browser, and use the couch interface to add data"
Create second database
This time, we're requesting shared access to $COUCH1
's volumes.
$ COUCH2=$(docker run -d -p 5984 --volumes-from $COUCH1 shykes/couchdb:2013-05-03)
Browse data on the second database
$ HOST=localhost
$ URL="http://$HOST:$(docker port $COUCH2 5984 | grep -o '[1-9][0-9]*$')/_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.
