Hashicorp Vault running inside Docker

Vault ina Dock

Example of Hashicorp Vault running inside Docker with HashiCorp Consul running in a cluster as the storage backend.

Only requires Docker, Docker Compose and a shell.

Building the Containers

Inside both consul and vault folders are build.sh scripts that will build minimal containers with only the Go binary downloaded from HashiCorp.

cd consul
./build.sh

cd vault
./build.sh

Importing root certs

The containers are so bare that they do not even have root certificates to verify the identity of AWS endpoints. to fix that run the following to extract a ca-bundle for your system.

./root-certs.sh

Usage

Once the containers are built run docker compose and the Consul cluster should be formed. Vault will be un-initialised.

docker-compose up

Once running initialise Vault with the init.sh script and its ready for (testing) use.

./init.sh

Backups

To backup the KV store and ACL from Consul (and all the Vault data with it) try at Consulate

TLS Certs

You can also create your own slef signed certificates and even use them for the communication to Consul and Vault and between the two. The gets stuck in a bootstrap cenario where you use Vault to generate the certificates but need certificates to start Vault. replace the "tls_..." lines with "tls_disable = 1" to start without TLS, generate your certificates and then stop and restart after reverting.

Redundancy Zones

run the following to set the meta flag

$ consul operator autopilot set-config  -redundancy-zone-tag=rz
