Docker Hub timeout in automated build on bionic based image

[gmatheu]

From https://stackoverflow.com/a/34588866/520275:

I've contacted their support team, and according to their response, the current limits on Automated Builds are:

• 2 hours
• 2 GB RAM
• 1 CPU
• 30 GB Disk Space

Alternatives are:

• Break them into several Automated Builds connected by FROM statements and Repository Links, or
• build them locally on your machine and push them to the repository
• use another build server
