    Purpose

Follow the steps below if you are interested in creating your own custom configurable Couchbase docker image. You will start off with the official Couchbase Enterprise docker image that is available on Docker Hub and use the Couchbase CLI and REST interface to create a custom configurable image.
Credits

This approach inspired by the tutorial. We  essentially built a custom docker image from the base Coucbase server image that is configured for our development needs!
Steps


Create a new file named DockerFile and open it using an editor of your choice
Now add the following lines to the DockerFile.

    FROM couchbase
    COPY configure-server.sh /opt/couchbase
    CMD ["/opt/couchbase/configure-server.sh"]

Create a new file named configure-server.sh an open it using an editor of your choice
Now add the following lines to the configure-server.sh. We are using the CLI and REST commands to configure the cluster, the Administrator user, the bucket and the RBAC user.
You can update this script according to your configuration needs.

   set -m

    /entrypoint.sh couchbase-server &

    sleep 15

    # Setup initial cluster/ Initialize Node
    couchbase-cli cluster-init -c 127.0.0.1 --cluster-name $CLUSTER_NAME --cluster-username $COUCHBASE_ADMINISTRATOR_USERNAME \
    --cluster-password $COUCHBASE_ADMINISTRATOR_PASSWORD --services data,index,query,fts --cluster-ramsize 256 --cluster-index-ramsize 256 \
    --cluster-fts-ramsize 256 --index-storage-setting default \

    # Setup Administrator username and password
    curl -v http://127.0.0.1:8091/settings/web -d port=8091 -d username=$COUCHBASE_ADMINISTRATOR_USERNAME -d password=$COUCHBASE_ADMINISTRATOR_PASSWORD


    sleep 15

    # Setup Bucket
    couchbase-cli bucket-create -c 127.0.0.1:8091 --username $COUCHBASE_ADMINISTRATOR_USERNAME \
    --password $COUCHBASE_ADMINISTRATOR_PASSWORD  --bucket $COUCHBASE_BUCKET --bucket-type couchbase \
    --bucket-ramsize 256

    sleep 15

    # Setup RBAC user using CLI
    couchbase-cli user-manage -c 127.0.0.1:8091 --username $COUCHBASE_ADMINISTRATOR_USERNAME --password $COUCHBASE_ADMINISTRATOR_PASSWORD \
    --set --rbac-username $COUCHBASE_RBAC_USERNAME --rbac-password $COUCHBASE_RBAC_PASSWORD --rbac-name $COUCHBASE_RBAC_NAME \
        --roles bucket_full_access[*],bucket_admin[*] --auth-domain local


    fg 1


Build the custom Docker Image using the DockerFile. The name of the image is couchbase-dev

    docker build -t couchbase-dev .

Once you have succesfully built the custom image, you can run it by providing the appropriate configuration options. Note that we have provided appropriate values for the parameters defined in the configure-server.sh file.

    $ docker run -d --name cb-server -p 8091-8094:8091-8094 -p 11210:11210 -e COUCHBASE_ADMINISTRATOR_USERNAME=Administrator -e COUCHBASE_ADMINISTRATOR_PASSWORD=password -e COUCHBASE_BUCKET=demobucket -e COUCHBASE_RBAC_USERNAME=admin -e COUCHBASE_RBAC_PASSWORD=password -e COUCHBASE_RBAC_NAME="admin" -e CLUSTER_NAME=demo-cluster couchbase-dev

You can view the logs at any time by running the following command

   docker logs -f cb-server
Sample

You can get a latest docker image of Couchbase Server  generated from the above script
  docker pull priyacouch/couchbase-dev
