Reaching a service from external applications

To be able to reach the entrypoints in your deployed services from external applications, the application has to authenticate itself. The applications require a valid authentication token which is generated by the MVI Manager.

Generate an Authentication Token

To generate this authentication token, you will need to use the CLI. Start by making sure that you are logged in by calling the login command:

>>> mvi login 
Enter MVI host: http://your-host
Username: <username>
Password: <password>

When you are logged in, use the token command:

>>> mvi token 
{your_token}

This will generate a long-lived authentication token. This means that this token remain valid indefinitely, which can potentially pose a security risk.

If you want a semi-long lived authentication, specify the number of days it should be valid by specifying an integer with your command call:

>>> mvi token 10 
{your_token}

This will generate a token that is valid for 10 days.

Using the Authentication Token

Once you have generated the authentication token for your external application you are ready to start sending requests to the deployed services.

The authentication token is used as a Bearer token and should be included in the header of the applications requests to the services as key-value pair, like this:

"Authorization: Bearer {your_token}"

For example, using the requests package in python:

json_data = {"data": "my_data"}

response = requests.post(
    "services/name_version/entrypoint",
    json=json_data,
    headers={"Authorization": f"Bearer {TOKEN}"})
