How to Utilize “docker run” Options?

The “docker run” command utilizes different options to behave differently and execute containers along with the different tasks. To utilize the different “docker run” command options, first, list down all supported options with the help of the “–help” option as shown below:

> docker run --help

From the below output, you can view all “docker run” supported options along with their relevant description:

After that, utilize the “docker run” options to execute containers in different manners.

To use the “docker run” command options, go through the below-provided examples.

Example 1: Run Container in Privileged Mode

In order to operate the Docker container with host privileges, check out the below-given command:

$ docker run --privileged -d -p 8080:8080 golang:alpine

In the above command, the following options are used:

  • privileged” flag is utilized to allocate the host privileges to the container
  • -d” is used to execute the container in the background
  • -p” is utilized to specify the exposing port for the container:

Example 2: Execute Container in Interactive Mode

To execute the container interactively, the “-i” option is used. Moreover, the “-t” flag allocates the pseudo-TTY terminal to the container:

> docker run -it docker-image

Example 3: Remove Container After Execution

To remove the container automatically after execution, the “docker run” command is used along with “–rm” command:

> docker run --rm golang:alpine

Example 4: Mount Volume to Container

To mount the volume or external file system to the container, follow the provided command:

> docker run -d --name go-container --mount source=my-golang-vol,target=/app golang:alpine


  • –name” is used to set the container name.
  • –mount” is utilized to mount or bind the volume.
  • source” variable specifies the source volume.
  • target” variable specifies the container’s targeted path:

That’s all about the “docker run” options.


Docker “run” command is a frequently used command to create and execute containers. It supports various options to execute the container in different manners, such as “–name” specifies the name of the container, “–mount” is used to mount the volume, “–rm” removes the container automatically, and many more. This write-up has elaborated on Docker “run” options and how to use them.
