Create a Docker secret, which stores the password of the ServiceNow user who will log into the instance to execute the tests. Docker Secrets is a feature of ServiceNow® for securely storing the passwords that will be used in containers.

Before you begin

Complete Step 3: Create the Docker image and containers for Headless Browser setup in Linux

Role required: none.

About this task

Inside of the Docker container is an automation script that opens a web browser, logs into the instance, and opens the client test runner page. In order to log into the ServiceNow instance, you will need a user password. In this procedure you use a Docker feature called Docker Secrets so you can securely store passwords. When you run containers, the password is automatically available to log in to your instance.

Role required: admin on your ServiceNow instance and local administrator on the host machine.

Procedure

At the command line, enter docker swarm init
Enter echo "<your user's password>" | docker secret create sn_password -

Note: Replace <your user's password> with the user's ServiceNow password.

Your results should look like this:

[Omitted image "echo-password.png"] Alt text: Results of entering echo "my password" code

Result

The result is your secret ID, which you must save for later use. The secret ID will be added to the ServiceNow instance in the sys_property sn_atf.headless.secret_id.

# Add secrets to Docker for Headless Browser setup in Linux

Create a Docker secret, which stores the password of the ServiceNow user who will log into the instance to execute the tests. Docker Secrets is a feature of ServiceNow® for securely storing the passwords that will be used in containers.

Role required: none.

## About this task

Inside of the Docker container is an automation script that opens a web browser, logs into the instance, and opens the client test runner page. In order to log into the ServiceNow instance, you will need a user password. In this procedure you use a Docker feature called **Docker Secrets** so you can securely store passwords. When you run containers, the password is automatically available to log in to your instance.

Role required: admin on your ServiceNow instance and local administrator on the host machine.

## Procedure

1.  At the command line, enter `docker swarm init`

2.  Enter `echo "<your user's password>" | docker secret create sn_password -`

    **Note:** Replace `<your user's password>` with the user's ServiceNow password.

    Your results should look like this:

    \[Omitted image "echo-password.png"\] Alt text: Results of entering echo "my password" code


## Result

The result is your secret ID, which you must save for later use. The secret ID will be added to the ServiceNow instance in the **sys\_property** `sn_atf.headless.secret_id`.
