Akamai Docker Development Environment Tutorial

This document provides examples on using the different packages, and more explanations for those not so familiar with Docker.

Starting Docker Containers for interactive use

Using docker run you can start an isolated docker container out of a docker image. There are several ways to use docker containers, for example:

Permanent container (keep the session alive)

You would start the container using docker run , than you add -it to indicate interactive, followed by --name and a name of your choice to be able to refer to that container later on easily.

The example below creates a docker container named akadev out of the docker image shell within the organization akamai:

docker run -it --name akadev akamai/shell

You can then exit the container, and start it later on using:

docker start -i akadev

The files inside this docker container will persist in the host machine until the container is destroyed using docker rm. Once you remove the container using docker rm all the files inside will be lost.

Permanent container (fresh session each time)

Sometimes you want to start a container fresh each time (without any leftover files from previous sessions). To do that, you would start the container using docker run , than you add -it to indicate interactive, followed by --rm to indicate the container should be removed upon exit. When using fresh containers, it is often very useful to mount one or more files (or a folders) from the host system into the container, like for example to mount the file .edgerc containing the Akamai OPEN API client credentials

The example below creates a docker container out of the docker image shell within the organization akamai, that will be cleaned up --rm and mounts the $HOME/.edgerc file from the host machine into /root/.edgerc in the container as read-only:

docker run --rm -it -v $HOME/.edgerc:/root/.edgerc:ro akamai/shell

Note: Notice in the above example we are not giving the docker container a name using --name, in that case docker will assign a random name that you can see running a docker ps command.

Another way to achieve the same result would be to first create a container using the command below:

docker run --rm -it -v $HOME/.edgerc:/root/.edgerc:ro akamai/shell

And then in another terminal window, run a docker ps to identify the docker container name (determined_borg in our example), and then copy the $HOME/.edgerc file into the container usingdocker cp:

docker ps

docker cp $HOME/.edgerc determined_borg:/root/.edgerc
