Mina is a constant-size blockchain written in OCaml. We were eager to try itprogramatically before their mainnet release.
We decided to give it a try in a Kubernetes cluster on Amazon EKS. Mina already maintains Helm charts, so deployment was easy.
We normally use Terraform, but we recently got familiar with Pulumi, a newer infrastructure-as-code framework. There are key differences with Terraform: while Terraform requires using its own DSL, Pulumi lets you use a variety of programming languages. That being said, the ecosystem seems to be mostly focused on TypeScript, so this is what we will be using.
Pulumi is a fairly recent project, born when Kubernetes use was already mainstream. A typical cloud deployment nowadays consists of a Kubernetes cluster as its core and some “satellite” cloud-specific services. It is very easy to deploy a cluster and a helm chart programatically with Pulumi: this is what we will be doing as part of this tutorial.
Deploy a block producer
Clone our mina-pulumi repository.
Login to the AWS cli using your account credentials.
Clone our Mina repository.
Install the Typescript dependencies:
Populate three files with your Testworld key:
in a file called key.pub
, write your public key
in a file called key
, write your encrypted private key
in a file called password
, write the password for your private key
Then simply run:
This will take some time since it will:
deploy an EKS cluster
Deploy the block-producer helm chart
Start the block producing container with your credentials
When done, you can export the kubeconfig file for your new cluster:
pulumi stack export kubeconfig > kubeconfig.yaml
Then launch k9s:
You will see your pod running:
You can press Enter to observe the containers, then press key down to select the install_key
container and observe that it succesfully imported your key:
Using password from environment variable CODA_PRIVKEY_PASS
Using coda keypair private-key password from environment variable CODA_PRIVKEY_PASS
😄 Imported account!
Public key: B62qnBJBhcEUC4i1Pfo5ko46Q4UXpnzA1TZwyePsPwWhudaEQ8Lw1FE stream closed
Then you may select the coda container and press s
key to open a shell.
coda client status
You should see your node in state “Bootstrapped” then “Catchup” and finally “Synced”.
Congratulations! You are now running a Mina node in the cloud.
We are a proof-of-stake infrastructure company. We create and maintain open-source framework for safe staking operations. We support the leading proof-of-stake cryptocurrencies: Tezos, Polkadot. We are eager to improve our Mina tooling to make it production-ready once the mainnet launches, and submit Helm chart improvements upstream as we go!
