What does SSH do to a remote host?
When using the SSH protocol for remote docker access what happens is that the docker client actually runs an ssh command on the local host, with a hidden docker command (docker system dial-stdio) on the remote host, that establishes a connection to the remote's dockerd endpoint which is almost always /var/run/docker.sock, and forward the connection to the commands stdio.

We will see that this is not a complex task either, if we re-use existing Docker images from Docker hub.

What Is Docker Remote Access?
Method 1: Setup Remote Docker Access Using Ssh
- One of the best thing about using SSHhere is that it requires a lot less work than the other method. If you already have SSH keys set up, it's literally a one-step process. Before moving forward I want you to have this mental picture in place, for understanding how this SSH method works, and why it's configured the way it's configured. To confirm the above statement, run any …
Method 2: Using A Public TCP Port with TLS Authentication
- This method is more complicate than the previous one, but has it's advantages like not having to use the dockergroup at all. The idea here is simple, you're going to create your own certificates and private keys, and then use a TCP port to access the dockerdaemon through not plain HTTP, but a secure HTTPS channel. It is analogous to a website. In case of a website, you configure it …
Preparing The Certificates and Keys
- In the following steps, you'll be generating certificates and private keys for your server and client. Certificate Authority To make the transactions simple, I'll be using my client machine to generate all the files. You can use a separate machine for that if necessary. A CA certificate is nothing but a self-signed certificate. But first, you need to generate your CA's private key. Use the following co…
Setting Up The Environment
- Once the certificates and private keys are ready, you need to tell your docker engine and client about them, along with exposing the engine API to a public TCP port and letting the client use the docker engine that's not sitting at the local machine. The following steps go through exactly that. The docker host First, copy over three files from the administrator's machine, the CA certificate (…
Test The Setup
- Now that everything is done, you can test it by running docker info, or run any random container, whichever comes to your mind. You can also use curl to test it (Remember? These are simple HTTP requests). Use the following as an alternative to docker info This will output a JSON object that you can parse using something like jq. You can also try and run an Nginx server with docker…
Which Method to use? TCP Or Ssh?
- Both methods has their own merits. The SSH method is easier if you don't want to go through many hoops. But some applications like Portainer won't work with the SSH method for remote daemon access. Using the TCP method also eliminates the issues of "using or not using the docker group" by default. Choose whichever method satisfies your purpose. I hope this tutorial …
