This is a trick that @eddiewebb finds handy to converry Hashicorp CLI responses into local environment variables that can be used in subequent commands (docker login,etc)

Prerequsities

an image with jq (all CCI images have it)
JSON respresenting values to convert to ENV VARs

Approach

We basically use jq as a rudimentary templating engine, converting existing k/v to shell format.

Code

Sample Payload

{
    "data":
    {
        "username":"agent_007",
        "password":"SuperSocks",
        "pin": "0000"
    }
}

Result

export AGENT_USERNAME='agent_007'
export AGENT_PASSWORD='SuperSocks'
export AGENT_PIN='0000'

JQ Command

jq -r '.data | to_entries[] | "export AGENT_"+(.key | ascii_upcase)+"="+(.value | @sh)' >> $BASH_ENV
source $BASH_ENV # only if needed in this step, evrry future step will load for us
