dshafik/memcached repository overview

⁠dshafik/memcached

This simple Dockerfile example will create an Ubuntu Wily based container with the memcached daemon.

⁠Building

To build issue the docker build command:

$ docker build -t $USER/memcached .

This will build the image, and tag it (-t) with <your username>/memcached.

⁠Verifying

To verify your new image has been built, run docker images:

$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
$USER/memcached   latest              001bac9e2c92        7 minutes ago       199.3 MB
ubuntu              wily                0fe5a10d2cf8        8 days ago          132.4 MB

⁠Running

To run the image, use the docker run command:

$ docker run -d -p 11211:11211 $USER/memcached

This will run the container daemonized (-d), and map the exposed memcached port to the docker host machine.

⁠Verifying

To verify the container is running use docker ps:

$ docker ps
CONTAINER ID        IMAGE                      COMMAND                CREATED             STATUS              PORTS                      NAMES
b713f32569da        dshafik/memcached:latest   "memcached -u daemon   9 minutes ago       Up 9 minutes        0.0.0.0:11211->11211/tcp   evil_cori

⁠Connecting to memcached

To connect to the memcached instance, simply use telnet. If you are using Linux, you should be able to simply connect to localhost. However, if you are using boot2docker you will need to get the boot2docker host IP using boot2docker ip:

⁠Linux

$ telnet 127.0.0.1 11211
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

⁠Boot2Docker

For Mac, use the following:

$ telnet `boot2docker ip` 11211
Trying 192.168.59.103...
Connected to 192.168.59.103.
Escape character is '^]'.

On Windows, you will need to install or enable a telnet client, and to get the IP by calling boot2gecko ip.

⁠Cleanup Images

To remove all images except the ubuntu/wiley base image, use the following:

docker images -q | grep -v 0fe5a10d2cf8 | xargs docker rmi -f
