Steps to deploy custom gem (Vault-ruby as example)

README.md

1. Clone git repository:

git clone [email protected]:stenio123/vault-ruby.git

2. Move to desired branch:

git checkout added-namespaces

3. Create gem:

gem build vault.gemspec

4. Install gem:

gem install ./vault-0.12.1.gem

5. Create test code:

# test.rb
require 'vault'

vault_client = Vault::Client.new(address: ENV["VAULT_ADDR"], token: ENV["VAULT_ADDR"], namespace: ENV["VAULT_NAMESPACE"])

# Edit the secret path as needed
secret = Vault.logical.read("secret/app1")
puts secret.data

6. Set environment variables accordingly:

export VAULT_ADDR=YOUR-VAULT-ADDRESS
# Note that the ruby gem can also look for the Vault token in ~/.vault-token if this env var is not set
export VAULT_TOKEN=YOUR-VAULT-TOKEN
export VAULT_NAMESPACE=YOUR-VAULT-NAMESPACE

7. Run the test code:

ruby test.rb
# Output:
{:test=>"secret"}
