⁠docker-serverspec

Docker container to run serverspec via Docker-in-Docker.

⁠Usage

Docker-ception in action:

$ docker pull nanliu/serverspec:alpine
$ docker run -v /var/run/docker.sock:/var/run/docker.sock \
  -it nanliu/serverspec:alpine /bin/sh

You should see all running containers in the serverspec container and all your docker images

# docker ps
CONTAINER ID        IMAGE                             COMMAND                  CREATED             STATUS              PORTS               NAMES

# docker images
...
# exit

Run a serverspec test:

$ git clone https://github.com/nanliu/docker-serverspec.git
$ cd docker-serverspec
$ docker run -v /var/run/docker.sock:/var/run/docker.sock \
  -v "$(pwd)":/serverspec \
  -it nanliu/serverspec:alpine /bin/sh -c "cd /serverspec && rspec snap_spec.rb"

Run a serverspec test with pry rescue:

$ cd docker-serverspec
$ docker run -v /var/run/docker.sock:/var/run/docker.sock \
  -v "$(pwd)":/serverspec \
  -it nanliu/serverspec:alpine /bin/sh -c "cd /serverspec && rescue rspec snap_spec.rb"

⁠Writing the Test

⁠Docker Metadata

Change snap/Dockerfile⁠ to a new maintainer (your own name)

MAINTAINER your name <[email protected]>

Update snap_spec.rb⁠ to match this change.

⁠Serverspec

Change the COPY entry in snap/Dockerfile⁠ to match the following:

COPY snapteld.conf /etc/snapteld.conf

Update snap_spec.rb⁠ to match this change.

this will cause the symlink tests to fail

Update snap/init_snap⁠ to match this change.

[ -f /etc/snap/snapd.conf ] || ln -s /etc/snapteld.conf /etc/snap/snapd.conf

⁠Run containers

Change the 'snap_spec.rb'⁠ to run the snap container directly instead of building it first.

hint:

describe docker_run('intelsdi/snap:alpine')
  #test
end

⁠Custom Test

Create mysql_spec.rb to test the dockerfile in mysql directory.

hint:

create mysql_spec.rb

$ vim mysql_spec.rb
describe docker_build('/serverspec/mysql/.')
  describe docker_run(described_image) do
    #test
  end
end

Test your spec:

$ cd docker-serverspec
$ docker run -v /var/run/docker.sock:/var/run/docker.sock \
  -v "$(pwd)":/serverspec \
  -it nanliu/serverspec:alpine /bin/sh -c "cd /serverspec && rspec mysql_spec.rb"
