gearmand Docker Images

The Dockerfiles under the testing subdirectory are intended to be used to test building gearmand on various Linux distributions. They also quasi-document the prerequisite packages that need to be installed on these same Linux distributions in order to build gearmand from source.

The example gearmand Docker image can be built like this:

cd example/supervisord/ && make latest && cd ../gearmand/ && make latest

The testing gearmand Docker images can be built like this, e.g.:

cd testing/alpine/3.12.0 && make

Using SSL

In order to use SSL with the example image, follow these steps before building the image using the above command:

1. Copy your certificate files to the gearmand subdirectory:

   cp /path/to/your/certificates/your-certificate-authority.pem example/gearmand/gearmand-ca.pem
   cp /path/to/your/certificates/gearmand.pem example/gearmand/gearmand.pem
   cp /path/to/your/certificates/gearmand.key example/gearmand/gearmand.key
   

Or, better yet, use Docker secrets.

1. Edit example/gearmand/Dockerfile and uncomment the line that copies these files to /var/lib/gearman/.

2. Edit example/gearmand/gearmand.conf and uncomment the command line with the SSL-related arguments. Delete (or comment out) the command line on the next line in that file.
