Indexer in Sandbox is Broken due to New Requirement of Follower Node

[tzaffi]

Add a Follower Node to Sandbox

This is a skeleton of an issue which hopefully will be resolved soon.

Q: I’ll be adding another node - a follower - and then have it serve only to indexer ?

Yes, exactly.

Q: Is the algod broken too?

No, it's perfectly fine, just doesn't work for the indexer as currently configured

TODO

• [ ] Add the follower to the same algod container
  • [ ] it should serve on a new port 4003 ???
  • [ ] indexer should read from that port
• [ ] (Optional) measure the memory / cpu / time requirements of sandbox algod container
  • [ ] as currently configured
  • [ ] with the follower node living in it too

Here is a proof of concept setting up the entire stack with off the shelf docker images:

we currently have a Docker container for algod and conduit. we still need a Docker container for indexer - prerequisite to this issue.

once we have that, then this ticket will create a docker-compose file that puts it all together for sandbox.

requires design.
