How to store Databricks token created from CLI in Yaml Bash step - azure-devops

Question

I have the following Yaml script. I am looking for how to grab the token created and store into a variable:
- bash: |
echo {} > ~/.databricks-connect#
source py37-venv/bin/activate
pip3 install wheel
pip3 install databricks-cli
displayName: Install Databricks CLI
- bash: |
source py37-venv/bin/activate
databricks configure --token <<EOF
${DATABRICKS_HOST}
${DATABRICKS_AAD_TOKEN}
EOF
databricks tokens create --lifetime-seconds 129600 --comment "My comment."
The response that the above command returns is this json:
{
"token_value": "dapi1a23b45678901cd2e3fa4bcde56f7890",
"token_info": {
"token_id": "1ab23cd45678e90123f4567abc8d9e012345fa67890123b45678cde90fa123b4",
"creation_time": 1621287738473,
"expiry_time": 1621417338473,
"comment": "My comment."
}
}
I want to store the value of token_value above so I can use it in another task below.

You can use jq to parse the response json to get token value, for example:
token=$(databricks tokens create --lifetime-seconds 129600 --comment "My comment." | jq .token_value --raw-output)
Set $token as variable with logging command(you can set it as secret or not,click the link to check the usage), then use it in next job($(setvar.databrickstoken)).
echo "##vso[task.setvariable variable=databrickstoken;issecret=true;isoutput=true]$token"
