After you see something like the above, run this:

sudo docker images

find the image ID - in this case it's 6808800d3546 and tag it:

sudo docker tag 6808800d3546 vaultalpha

This is the output with the assigned name tag to the newly created image

Once you pull the image, you'll need to run it. And open another terminal to run docker exec to enter the container and launch vault.

1) Run the container

sudo docker run -i -t --rm --entrypoint sh --cap-add IPC_LOCK vaultalpha

In a new terminal window, exec a shell (grab the image that is running from above command).

docker ps -a

CONTAINER ID        IMAGE                              COMMAND                CREATED             STATUS                    PORTS               NAMES
734e7952e070        sometheycallme/vaultalpha:latest   "sh c"                 11 hours ago        Running         

Grab the ID

sudo docker exec -it 734e7952e070 sh

2) Initialize it and grab the keys - you need them to open the vault!

Once you have a separate shell exec'd go ahead and init

/ # vault init 
Key 1: 21f086ce697f5b5f8635d07d34b35c9124d043e3654d5df2dbe29f5da4d4979c01

Initial Root Token: 112f9aa7-352f-a988-76d2-66f08599013e

Vault initialized with 5 keys and a key threshold of 3!

3) Unseal the vault with any 3 of 5 keys 3

/ # vault unseal 21f086ce697f5b5f8635d07d34b35c9124d043e3654d5df2dbe29f5da4d4979c01
/ # vault unseal 56ecee66b02c8d4ccf7428e26a84e75477170243cc1f721d0033dc0dba9ede2903
/ # vault unseal 09992094c82bb66ffeef7b5553109d93d9bff00fb2b3bb173c096aefecf887b805

4) Authenticate to the vault with root

/ # vault auth 112f9aa7-352f-a988-76d2-66f08599013e

Successfully authenticated! The policies that are associated
with this token are listed below:


5) Finally, test reading and writing secrets

Write it

/ # vault write secret/foo password=bar lease=1h
Success! Data written to: secret/foo

Read it

/ # vault read secret/foo
Key                Value
lease_id           secret/foo/37d4cfb7-98c0-e330-eb32-32c916d326ca
lease_duration     3600
lease_renewable    %!d(string=true)
lease              1h
password           bar
