Docker for Datapower

Here is the link to install a Datapower docker image. This seems to work while I had it running on my OpenSuse Linux. I tried to install the same on in Windows 10 and it did not work. Please bear in mind that I did not have Microsoft HyperV installed on my machine it being a Home edition. I had to install Docker Toolbox and that installed Oracle Virtual Box along with it.

The resolution for the problem I found in the following link.

Make sure that the library path has the 32 or 64 bit depending on your configuration in the path i.e. -

export LD_LIBRARY_PATH=/opt/mqm/java/lib/:$LD_LIBRARY_PATH

Creating users for apache-tomcat

This will create the user tomcat with password s3cret.
