Reproducible infrastructure for Ethermint validators.

Requirements

• Terraform
• Packer

Build images

To build the images used for the machines run the provided build script (bin/build).

In order to successfully build, you need to specify the following environment variables

• DO_TOKEN: Your DigitalOcean API token
• DO_REGION: A valid DigitalOcean region slug where the built image will be available and the build droplet will run.

Deploy infrastructure

To deploy the infrastructure use Terraform directly or the provided helper script (bin/deploy).

For now you need to generate keys for the validator and put these keys in the data directory.

ethermintcli keys add $KEY --algo "eth_secp256k1"

Each keyfile should retain their original name as specified by Ethermint.

Furthermore, you will also need to either create a genesis file or fetch one for the network you want to operate on.

Parts of this procedure might be automated in the future.

Full example

# Generate the genesis file

# Generate the keys

# Build images and deploy the infrastructure
DO_TOKEN=my-token DO_REGION=nyc3 ./bin/deploy
