<blockquote>
 The docker create command creates a writeable container layer over the
 specified image and prepares it for running the specified command. The
 container ID is then printed to STDOUT. This is similar to docker run
 -d except the container is never started. You can then use the docker start command to start the container at any point.
 
 This is useful when you want to set up a container configuration ahead
 of time so that it is ready to start when you need it. The initial
 status of the new container is created.

The other answers have this covered but I thought I'd show the equivalent shell command-lines because it makes it really clear:

<pre><code>$ docker run myimage
</code></pre>

is the same as

<pre><code>$ docker start -a $(docker create myimage)
</code></pre>

Here, <code>docker create</code> is used to create a container from the named image and outputs the created container id and <code>docker start</code> is used to start the container with that id. The <code>-a</code> option causes the terminal to attach so that the container runs in the foreground which is the default behaviour of <code>docker run</code>.

A container that has been created but never started will have a <code>Created</code> status; this can be seen with <code>docker container ls -a</code>.

I'm new to docker and just got around to playing with it; 

My take is that docker run essentially does the following: (in the order of..) docker create, docker start, docker attach , since it immediately attaches to the active shell after you do the 'run' command.

to create a container:
<a href="https://i.stack.imgur.com/ApT9E.png" rel="noreferrer"><img src="https://i.stack.imgur.com/ApT9E.png" alt="enter image description here" /></a>
to start a container:
<a href="https://i.stack.imgur.com/Isaz2.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Isaz2.png" alt="enter image description here" /></a>
to create and start with a single command:
<a href="https://i.stack.imgur.com/cu7ug.png" rel="noreferrer"><img src="https://i.stack.imgur.com/cu7ug.png" alt="enter image description here" /></a>
Now to understand we must dig deep with create and start.
Process of creating a container is taking the file system from image, and kind of prep it for use in the new container. When we create the container we are just prepping or setting up the file system snapshot to be used to create the container to actually start the container.
<a href="https://i.stack.imgur.com/yXifi.png" rel="noreferrer"><img src="https://i.stack.imgur.com/yXifi.png" alt="enter image description here" /></a>
So creating container is about the file system starting it is about actually executing the startup the command.
And to start the container, we actually execute the start up command that might start up the process.
Lets see it in terminal:
When I run command &quot;sudo docker create hello-world&quot; it prints bellow output.
<a href="https://i.stack.imgur.com/fVkw4.png" rel="noreferrer"><img src="https://i.stack.imgur.com/fVkw4.png" alt="enter image description here" /></a>
In the output we saw characters printed out. This is the ID of the container that was just created, Now I can actually execute the hello world command inside of this container by running Docker start.
<a href="https://i.stack.imgur.com/ZHhCC.png" rel="noreferrer"><img src="https://i.stack.imgur.com/ZHhCC.png" alt="enter image description here" /></a>
So what happened here, first off we kind of prop the container by getting the file system ready.
Then after that we actually executed the primary start up command in there with Docker start.
-a in the docker start command is for watching output from the container and print it out to your terminal.
So there is very small difference between Docker run and docker start, by default Docker run is going to show you all the logs or all the information coming out of the container. By default Docker start is the opposite Docker start is not going to show you information coming out of the terminal.
Now you know when you need to use Run / Create / Start

Docker run is basically for running commands in the container.

<pre><code>docker run -it &lt;Container Name&gt; /bin/bash
</code></pre>

The above is for creating a bash terminal. And make us use bash commands in the container.

Docker create is to create a container from an Docker Image.

<pre><code>docker create -d /var/lib:/var/lib --name docker-ubuntu ubuntu
</code></pre>

The above is to create a docker a container of the name "docker-ubuntu" from the image "ubuntu"

What is the difference between <code>docker run</code> and <code>docker create</code> commands?

I usually use <code>run</code> but sometimes in documentation I see <code>create</code>.

Docker's <code>--help</code> tells

<pre><code>create Create a new container
run Run a command in a new container
</code></pre>

Does it mean that <code>run</code> is used when we need to pass a command to a new container? What's the aim of <code>create</code> then?

docker run和docker create命令有什么区别？我通常使用run，但有时在文档中我看到了create。道克的--help告诉create    Create a new containerrun       Run a command in a new container这是否意味着当我们需要向新容器传递命令时使用run？那么，create的目标是什么？
