Connect to the Docker API
Before you begin, you will need to ensure that your Docker instance is configured to admit remote connections. To learn how to do this, refer to Docker's own documentation. Once Docker is configured, you will be able to connect either with or without TLS.
From the menu select Environments then click Add environment.
Next, select Docker Standalone as the environment type then click Start Wizard. Select the API option and your platform, then enter the environment details using the table below as a guide:
Portainer expects TLS certificates and keys to be in PEM format.
When you're ready, click Connect. If you have other environments to configure click Next to proceed, otherwise click Close to return to the list of environments.
