Failed to execute goal com.spotify:docker-maven-plugin unauthorized: authentication required

[dchucks]

I am sorry if this is a Docker newbie question. I am using Docker Toolbox with VirtualBox (as Hyper-V is not supported on my HP Laptop having Win Home edition OS). When I run the mvn clean installcommand I get error on the "users-microservice" and rest all Microservice build are therefore skipped. I am sure I must be doing something silly here, would appreciate your help.

This somehow got sorted out (I added the Server details of Docker Hub, as discussed in this stackoverflow thread) and the build worked. However, I was unable to have Docker compose spawn all the containers for me, but that perhaps is another topic and needs further work from me.

By increasing the memory allocated to VMs to 5GB (as already suggested in the article) I was able to run all the services in their containers. Kudos! Now to studying the code on all this magic. Many thanks.
