This installation procedure is written for users who are unfamiliar with package managers. If you are comfortable with package managers, prefer not to use curl, or have problems installing and want to troubleshoot, please use our apt and yumrepositories instead for your installation.
Log into your Ubuntu installation as a user with sudo privileges.
Verify that you have curl installed.
$ which curl
If curl isn’t installed, install it after updating your manager:
$ sudo apt-get update $ sudo apt-get install curl
Get the latest Docker package.
$ curl -fsSL https://get.docker.com/ | sh
The system prompts you for your sudo password. Then, it downloads and installs Docker and its dependencies.
Note: If your company is behind a filtering proxy, you may find that the apt-key command fails for the Docker repo during installation. To work around this, add the key directly using the following:
$ curl -fsSL https://get.docker.com/gpg | sudo apt-key add -
Verify docker is installed correctly.
$ docker run hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world 535020c3e8ad: Pull complete af340544ed62: Pull complete Digest: sha256:a68868bfe696c00866942e8f5ca39e3e31b79c1e50feaee4ce5e28df2f051d5c Status: Downloaded newer image for hello-world:latest Hello from Docker. This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker Engine CLI client contacted the Docker Engine daemon. 2. The Docker Engine daemon pulled the "hello-world" image from the Docker Hub. 3. The Docker Engine daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker Engine daemon streamed that output to the Docker Engine CLI client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker Hub account: https://hub.docker.com For more examples and ideas, visit: https://docs.docker.com/userguide/
