Encrypt/decrypt ansible vault file

A vault file contains sensitive information so that we shouldn't commit to source control in plaintext. So we need to encrypt it before committing to source control. Using Ansible vault so this problem.

Run below command to decrypt vault.yml file in the inventory directory

ansible-vault decrypt inventories/dev/group_vars/vault.yml --vault-password-file ansible-vault.pass

Make change required for your setting and encrypt using below command

ansible-vault encrypt inventories/dev/group_vars/vault.yml --vault-password-file ansible-vault.pass

Install and configure Neo4j Server

• Install Neo4j single server by running below command

Run below command to deploy a single Neo4j instance for dev environment. Replace dev to any existing inventory in the inventories directory (i.e. staging, prod)

ansible-playbook neo4j.single.yml -e env=dev --vault-password-file ansible-vault.pass

#  or we can use -b -K to enter SUDO password (sudo su)
ansible-playbook neo4j.single.yml -e env=dev --vault-password-file ansible-vault.pass -b -K

NOTE - you shouldn't check in the ansible-vault.pass file to source control
