Run the below code to get a vault container up and running. Use the config.hcl file to set the settings. The path below will look for that file.
docker run -p 8200:8200 -d -v /Users/mneepe1/test2/vaulttesting/vault/config:/vault/config --cap-add=IPC_LOCK -e "VAULT_ADDR=http://127.0.0.1:8200" vault server
Change Port and volume path to run a second container
docker run -d --name=secondaryvault -p 8222:8200 -v /Users/mneepe1/test2/vaulttesting/vault/config:/vault/config --cap-add=IPC_LOCK -e "VAULT_ADDR=http://127.0.0.1:8200" vault server
