Add a Docker Standalone endpoint
When connecting a Docker Standalone host to Portainer, there are two methods you can use. You can either connect directly to the Docker API via TCP, or you can install the Portainer Agent on the Docker Standalone host and connect via the agent.

Method 1: Connecting via 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.

Option 1: Connecting without TLS

From the menu select Endpoints then click Add endpoint.
Next, select Docker as the environment type then enter the environment details using the table below as a guide:
Field/Option
Overview
Name
Give the endpoint a descriptive name.
Connect via socket
Leave this option toggled off.
Endpoint URL
Enter the DNS name or IP address to connect to the Docker host along with the port. When connecting without TLS, the default port is 2375.
Public IP
Enter the URL or IP address where exposed containers will be reachable. This is an optional field (defaults to the endpoint URL).
TLS
Leave this option toggled off.
In the Metadata section, as an optional step you can categorize the endpoint by adding it to a group or tagging it for better searchability.
When you're ready, click Add endpoint.

Option 2: Connecting with TLS

Portainer can connect to the Docker host API using TLS. To use this option, the Docker environment you are connecting to must be configured to use TLS. Find out how to protect a Docker environment with TLS in Docker's own documentation.
From the menu select Endpoints then click Add endpoint.
From the Environment type section select Docker, then enter the environment details using the table below as a guide:
Field/Option
Overview
Name
Give the endpoint a descriptive name.
Connect via socket
Leave this option toggled off.
Endpoint URL
Enter the DNS name or IP address to connect to the Docker host along with the port. When connecting with TLS, the default port is 2376.
Public IP
Enter the URL or IP address where exposed containers will be reachable. This is an optional field (defaults to the endpoint URL).
TLS
Toggle this option on then select the TLS mode.
Field/Option
Overview
TLS mode
Select the mode that best fits your configuration. In most cases, this will be the default TLS with server and client verification option. The next options change, depending on what you select here.
TLS CA certificate
Select your CA certificate.
TLS certificate
Select your certificate.
TLS key
Select the key that matches the certificate.
Portainer expects TLS certificates and keys to be in PEM format.
In the Metadata section, as an optional step you can categorize the endpoint by adding it to a group or tagging it for better searchability.
When you're ready click Add endpoint.

Method 2: Connecting via the Portainer Agent

First, install the Portainer Agent on your Docker Standalone instance using our platform-specific instructions. When this is done, you will be able to add the endpoint to Portainer.
From the menu select Endpoints then click Add endpoint.
From the Environment type section, select Agent. Since we have already installed the agent you can ignore the sample commands in the Information section. Enter the environment details, using the table below as a guide:
Field/Option
Overview
Name
Give the endpoint a descriptive name.
Endpoint URL
Enter the DNS name or IP address to connect to the Portainer Agent along with the port (the default port is 9001).
Public IP
Enter the URL or IP address where exposed containers will be reachable. This is an optional field (defaults to the endpoint URL).
In the Metadata section, as an optional step you can categorize the endpoint by adding it to a group or tagging it for better searchability.
When you're ready, click Add endpoint.
