Running docker/build.sh VERSION will:

• build assembly (fat) jars
• create and push docker images (access right to magneticio Docker repository required) with specified VERSION

A/B testing different themes:

• Sava Monolith 1.0 + Sava Monolith 1.1 with router filters and weights (e.g. by browser type).

Steps:

• deploy sava_1.0.yaml
• add to the deployment sava_1.1.yaml
• adjust weights and filters
• adjust weight to 100% for 1.1 and remove the 1.0 from the deployment (using sava_1.0.yaml)

Topology change:

• Starting with micro-services and over-engineering it (3 services): from Sava 1.x to 3 service deployment Sava Frontend 1.2 & 2 Sava Backend 1.2.
• Moving back to more reasonable micro-services setup (2 services): from Sava Frontend 1.2 and 2 backends to deployment of Sava Frontend 1.3 and single Sava Backend 1.3.

Steps:

• deploy sava_1.2.yaml
• add to the deployment sava_1.3.yaml
• adjust weights and filters
• adjust weight to 100% for 1.3 and remove the 1.2 from the deployment (using sava_1.2.yaml)
