Start Testnet section

[ethanfrey]

Add a new testnets section to the docs.

Add two pages there:

• Demo Net
• Build Requirements

Demo Net page

Demo Net should contain info to point to how to deploy to the current demo net, as well as the binaries / client libs involved:

• wasmd v0.9.1
• cosmjs v0.21.1

Client endpoints (from @cosmjs/cli):

• https://lcd.demo-09.cosmwasm.com
• https://rpc.demo-09.cosmwasm.com
• https://faucet.demo-09.cosmwasm.com/credit (point to faucet usage docs

Show how to connect from local node:

• P2P endpoint: p2p.demo-09.cosmwasm.com:26656
• Node ID: (from wasmd tendermint show-node-id): 26c9c79dc62b5ddc753bb9fcce022fcc98b5a8cf
• Genesis: curl https://rpc.demo-09.cosmwasm.com/genesis | jq .result.genesis

Explain how to run with the official docker file (also use this locally and connect to the p2p node to show we can connect and sync)

Build Requirements

System requirements: We use a Digital Ocean 2CPU,4GB instance - consider that as good basis (see demo-net setup)

Building code may require larger instances, especially if you want to build a static instance (recompile rust code).

Simplest:

Use docker image, or build locally: https://github.com/CosmWasm/wasmd/#dockerized

Bare Metal:

Option 1 (prefered - static binary - Linux only):

• Download Dockerfile / build locally
• Copy the static binary out of it. (Try a command to do so)
• Use that static binary on any bare metal linux box

Constructing this is a tricky process and involves using alpine linux and recompiling the rust dependencies as static libs. I suggest you use the Dockerfile for that

Option 2: (dev-style: dynamic binary - works on Linux and OSX)

• Compile dev build (make build).
• ldd build/wasmd
  • notice the line like: libgo_cosmwasm.so => /home/USERNAME/go/pkg/mod/github.com/!cosm!wasm/go-cosmwasm@v0.9.1/api/libgo_cosmwasm.so
  • that file must be in the library path along with wasmd
• copy wasmd to any location on the target system (that will run the node)
• copy libgo_cosmwasm.so (path above) to the target system under `/usr/lib/libgo_cosmwasm.so

[webmaster128]

Since this lives under the cosmwasm.com domain/documentation, I assume this is not for the gaia testnet, right?

[ethanfrey]

This is general documentation for our networks right now (how to connect, how to use), as well as a list of endpoints for the testnets we run.

I would focus on our public testnet (demo net now, later the Aug 11th one) for devs, but I would just make a page here for the gaia testnet to keep it simple. They can all use the same references on how to build validators and connect
