vault

Vault is a tool for securely accessing secrets. A secret is anything that you want to tightly control access to, such as API keys, passwords, certificates, and more. Vault provides a unified interface to any secret, while providing tight access control and recording a detailed audit log.

server

$ cd ~/fig/vault
$ mkdir vault
$ openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout vault/vault.key -out vault/vault.crt
$ docker-compose up -d
$ docker cp vault_vault_1:/usr/bin/vault /usr/local/bin/

client

$ export VAULT_ADDR='https://127.0.0.1:8200'
$ vault status
$ vault init | tee vault.secret
$ vault unseal
$ vault auth
$ vault write secret/name key=value
$ vault read secret/name

• Split vault.secret, keep them a secret.
• Run vault unseal 3 times to unseal.
• Use key=@value to read secret from file.
