avalancheup-aws: Document state management for spot instances.

hexfusion commented 1 year ago

First of all avalancheup-aws is a nice tool it helped me quickly setup nodes on AWS. While working on creating a new subnet and blockchain I noticed that the AvalancheGo version that was installed 1.10.0 was less than the version I needed 1.10,2. Once I pulled in a new binary and installed it things worked fine. Also during debug I updated the system unit file for AvalancheGo.

The issue is when the system gets migrated I assume due to spot workflow.

I no longer have a systemd unit file for AvalancheGo
The binary returns to the old version

I have not dug into this much but I assume this is related to how the state is managed in the spot instances. When a new VM is started it pulls the binary from s3 and probably the unit file as well.

A short section in the docs would be useful describing.

how to upgrade AvalancheGo
how to update managed files
brief description of how spot works in this context.

On restart, the init script will rewrite the avalanchego systemd file (done by avalanched).

Yes, we need documentation.
