Public networks

[nicolasochem]

This introduces a third mode of operation. We previously had zerotier-in-use true/false.

Now we have public/private/isolated networks. Description is in README.

The main addition is the capability to run mainnet or a testnet on tezos-k8s, and sync quickly thanks to snapshots.

Add a new container to import snapshot. Make the assmption of a public network will run in rolling mode.

The config-generator container is now built on top of the tezos container. The reason is that we need to extract the network data from the binary to put it in the bootstrap_peers section. Entrypoint is now a shell script which calls the previous python entrypoint.

To test on edo2net, the master_328bc6c3_20210215194506 branch will work. Replace v8-release with this branch everywhere.

Then you need to submit network: edo2net in the values.yaml. We also add --network support to mkchain.

We switch the default protocol to edo2 because this is the one that runs in mainnet now.

Config-generator was previously using argparse to build config.json because it was originally part of mkchain. We replace it with a simple python object creation.

Black changed the formatting of some of Roland's crypto code for some reason.

If approved, I will be using "squash-and-merge" to merge.

IMO we should make the chain_types constants somehow. This way it is explicit what are acceptable values. And also so that we don’t have to keep referencing strings everywhere which can very easily introduce bugs. (e.g. hashs/hashes)

We can maybe have 3 (maybe just 2) vals: is_private, is_isolated, is_public. We can prob just go with the first 2. If NOT private AND NOT isolated, then it must be public. These vals get set by mkchain or whatever.

Or we can keep the eq checks in Helm templates but set “private” as a string Helm value. so private: "private" and check based off of that constant.

I don't think we should have is_isolated and is_private because then they would not be mutually exclusive.

What do you recommend? Something like:

{{ $chain_type_private := "private }}
{{ $chain_type_isolated := "isolated" }}
{{ $chain_type_public := "public" }}

Then

{{- if eq .Values.chain_type $chain_type_private }}

?

Yes something like that although I don't think that exact thing will work. Those variables won't be global to all templates.

I think there are a couple of options:

• Define global values: https://helm.sh/docs/chart_template_guide/subcharts_and_globals/#global-chart-values
• Define helpers in a .tpl file in charts/tezos/templates. This will contain templates with something like this:

  {{ define "tezos.public_chain" }}
  {{- "public" -}}
  {{ end }}

  Then we can compare on including the template. I think there is a way to treat the template like a function where you can pass a context in and let it spit back out a value like true/false that we can then just if on.

Either way, probably not necessary for getting the F-beta net out the door.
