[Research] Decrease Docker build time

[niraymak]

Is your feature request related to a problem? Please describe. Our build time of Docker compose is quite long. Jurjen told me that our build time can be decreased by applying caching. Also adding .dockerignore could improve the build time.

Describe the solution you'd like Research how we can improve the build time in our situation.
