Automated build of Varnish
Full Description

Automated build of Varnish with Docker

Varnish environment variables

Varnish will make of the following environment variables.


Use the pre built image

The pre built image can be downloaded using docker directly. After that you do not need to use this command again, you will have the image on your machine.

$ docker pull jacksoncage/varnish

Build the docker image by yourself

If you prefer you can easily build the docker image by yourself. After this the image is ready for use on your machine and can be used for multiple starts.

$ cd varnish-docker
$ docker build -t jacksoncage/varnish .

Start the container

The container has all pre requisites set up to run any varnish application. Specify all needed environment variables.

$ docker run -i -d -p 80 -e VARNISH_BACKEND_PORT=8080 -v /etc/localtime:/etc/localtime jacksoncage/varnish

Start the container and keep control

The command above starts the container in deamon mode (-d) and runs in the background. If you want to start it by yourself just to see what happens use this command:

$ docker run -i -t -p 80 -e VARNISH_BACKEND_PORT=8080 jacksoncage/varnish bash

Notice the two changes made here, first we replaced the deamon switch (-d) with the tty switch (-t) which pipes the std in and std out to your terminal.

You now end up as a root user in the docker container and can do simple things like ls, cd and more. More complex things can be achieved after a apt-get install of one or more software(s) of choice.

Get the container ip and port

The first command inspects your created container and get the IPv4 address. Second command docker exported port for 8080.

$ docker inspect <container_id> | grep IPAddress | cut -d '"' -f 4
$ docker port <container_id> 80 | cut -d ":" -f2

Now go to <your container's ip>:<container's port> in your browser

Stop the container

Stopping a running container is possible via the docker api. If only one instance of this container is running this command will stop it:

$ docker stop `docker ps |grep jacksoncage/varnish |cut -d\  -f1`
Docker Pull Command

I really appreciate this image. It would be perfect if you can add tags for different versions of varnish (3.x, 4.x)
