Scripts used by DevOps team at Vega

This repository contains shared packages imported and used by scripts in other repositories.

Setup

Create secret.txt in root directory of this repo, and put your GitHub token inside. (the scope of the token does not matter).

Reason: some of the commands require secrets (vega or eth wallets, or node secrets). Those are read automatically from HashiCorp Vault. We use GitHub authentication for HashiCorp Vault.

DevOps goals

We want to minimise usage of bash and replace it with Golang.

We assume that:

• we have Go installed on every machine
• we run our scripts go run main.go ... fashion, instead of: tag version->complie->publish->download->run
• we use cobra to manage all CLI aspects

Usual use-case

In a repo we create scripts directory, where we put DevOps Go scripts.

Example:

# Script to download latest checkpoint
go run scripts/main.go checkpoint download-latest --network fairground

The logic of that specific script is kept in scripts/cmd/checkpoint.go in that repository (or similar structure). Shared functionality used by that script (like list of nodes, ssh to machine or download file) is imported from devopstools repo (i.e. here).

Useful commands

Some useful commands not connected to any particular repo, are kept here.

Execute command on every node

    ops pssh \
    --ssh-user fryderyk \
    --ssh-private-keyfile ~/.ssh/id_ed25519 \

    --command "pwd"
