lxc exec {}-vault -- /opt/gbo/bin/vault operator init
This will output 5 unseal keys and 1 root token.
Copy at least 3 unseal keys to your .env file for auto-unseal on restart.
Save at least 3 unseal keys to the secrets file for auto-unseal on restart.
Add to your .env file:
Step 1: Add to your .env file:
VAULT_ADDR=http://{}:8200
VAULT_TOKEN=<root-token-from-init>
VAULT_UNSEAL_KEY_1=<unseal-key-1>
VAULT_UNSEAL_KEY_2=<unseal-key-2>

VAULT_UNSEAL_KEYS_FILE=/opt/gbo/secrets/vault-unseal-keys
botserver will automatically unseal Vault on startup using these keys."#,
Step 2: Create secrets file (chmod 600 for security):
mkdir -p /opt/gbo/secrets
cat > /opt/gbo/secrets/vault-unseal-keys << 'EOF'
VAULT_UNSEAL_KEY_1=<unseal-key-1-from-init>
VAULT_UNSEAL_KEY_2=<unseal-key-2-from-init>

chmod 600 /opt/gbo/secrets/vault-unseal-keys
chown root:root /opt/gbo/secrets/vault-unseal-keys
botserver will automatically unseal Vault on startup using keys from this file.
