Use containerized applications in Avni

[himeshr]

Avni load-balancing, networking and system update considerations

• Growing number of application modules which we have in Avni (avni-server, rules-server, avni-webapp, avni-media-server, avni-media-client, etl, avni-integration-service and avni-int-admin-app, keycloak, Minio)
• The need for these modules to easily interact with each other over network
• The need to ease of deployment and maintenance of these app modules
• Optimize resource utilization
• Load-balancing needs that might arise in future
• Reporting software upgrades
• SSL certificates upgrades and using a single chained one

Proposed solution:

In-order to handle the above considerations, we should seriously consider using Docker Containers and Kubernetes clusters along with some auth layer rework of Avni

Create docker container config for avni apps - 20d

• avni-server - 2d
• webapp - 2d
• rules-server - 2d
• integration-service - 1d
• integration-admin-app -1d
• etl - 2d
• avni-media-server - 1d
• avni-media-client - 1d
• keycloak - 1d
• Minio - 1d
• JasperServer - 2d
• Metabase - 2d
• Superset - 2d

Create Kubernetes config for Avni - 22d

• Create docker hub - 0
• Load-balancers - 3d
• network config for inter app communication - 5d
• Reverse-proxy - 2d
• services - 3d
• deployments - 5d
• HorizontalPodAutoscaler for few apps - 2d
• SSL cert in-front of ReverseProxy - 2d

Handle logging, uptime and debugging aspects - 5d

Handle build and deploy of applications using CirceCI(or other CI tools) - 10d

Setup staging env using kubernetes - 2d

Setup Prod env using kubernetes - 2d

Switch Prod DB from avni-server standalone to kubernetes avni-server. - 2d
