How I built couchbase 2.2 for docker

coreos.script

#!/bin/sh

int=`ip route | awk '/^default/ { print $5 }'`
addr=`ip route | egrep "^[0-9].*$int" | awk '{ print $9 }'`

mkdir -p /home/core/data/couchbase
sudo chown 999:999 /home/core/data/couchbase

exec sudo docker run -i -d -t -e DOCKER_EXT_ADDR=$addr \
    -v /home/core/data/couchbase:/opt/couchbase/var \
    -p 11210:11210 -p 8091:7081 -p 8092:8092 \
    dustin/couchbase

couchbase-script

#!/bin/sh

untilsuccessful() {
    "$@"
    while [ $? -ne 0 ]
    do
	    echo Retrying...
	    sleep 1
        "$@"
    done
}

cd /opt/couchbase

Hi! When I try to start this docker image using the commands you listed on the docker registry:
mkdir -p /home/core/data/couchbase
sudo chown 999:999 /home/core/data/couchbase
sudo docker run -i -d -t -v /home/core/data/couchbase:/opt/couchbase/var -p 11210:11210 -p 8091:7081 -p 8092:8092 dustin/couchbase

I get the error "Error: No command specified". If I append a /bin/bash or something to that effect to the end, I don't get the error, but the docker image doesn't appear to keep running either.

Well, apparently I get comments here. I had no idea. sigh

I don't actually know why it would say there's no command specified. There's clearly one in the Dockerfile. :/ I did confirm it happens with the published image, though. I'll fix this.

fwiw, i was able to get that working by first doing:

sudo docker pull dustin/couchbase

and then use the id it gives (get using sudo docker images) instead of using dustin/couchbase in the run command.

There was some confusion between :2.2 and :latest. I think it's all sorted now.

Thank you Dustin for this example. I would also recommend an rebalance after add server (untilsuccessful /opt/couchbase/bin/couchbase-cli server-add -c $ALPHA_PORT_7081_TCP_ADDR:8091
--user=Administrator --password=password --server-add=$addr:8091)
