If you are using a different system, please check our other tutorials.
Rancher is an open source platform for running containers and building a private container service. Rancher is based on Docker, so you can run it on a dedicated box, KVM machine or even on a LXC container. Rancher provides a huge library of applications which are installed within a few clicks and also supports Docker images from Dockerhub.
- An ITWeb.Services instance Ubuntu 16.04 x64.
- At least 1GB memory.
- A supported version of Docker.
As stated, Docker is required to run Rancher, so we will install it first.
First, remove any old Docker files, if necessary.
sudo apt-get remove docker docker-engine docker.io
Note: You may get a report that no Docker files are installed. This is safe to ignore.
Update package lists.
sudo apt-get update
apt to use a repository over
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
Add the official GPG key.
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
Verify that you have the key by searching for last 8 digits of the key’s fingerprint.
sudo apt-key fingerprint 0EBFCD88
The output will resemble the following text.
pub 4096R/0EBFCD88 2017-02-22 Key fingerprint = 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88 uid Docker Release (CE deb) <email@example.com> sub 4096R/F273FCD8 2017-02-22
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
Update package lists again.
sudo apt-get update
Check the available versions of Docker CE.
apt-cache madison docker-ce
You will see output similar to the following block.
docker-ce | 17.09.1~ce-0~ubuntu | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages docker-ce | 17.09.0~ce-0~ubuntu | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages docker-ce | 17.06.2~ce-0~ubuntu | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages docker-ce | 17.06.1~ce-0~ubuntu | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages docker-ce | 17.06.0~ce-0~ubuntu | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages docker-ce | 17.03.2~ce-0~ubuntu-xenial | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages docker-ce | 17.03.1~ce-0~ubuntu-xenial | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages docker-ce | 17.03.0~ce-0~ubuntu-xenial | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages
version-string, (second column), of the latest stable version after the
= in the following command to install the latest version of Docker CE.
sudo apt-get install docker-ce=17.09.1~ce-0~ubuntu
Note: You can install the latest version of Docker CE without appending the version to the end of the
sudo apt-get install docker-ce command, but in a production environment, I recommended that you install a specific version rather than the latest version.
Verify that Docker installed correctly.
sudo docker run hello-world
This command runs a test image in a test container to print a message, then exits. The message will be similar to the following output.
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 client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (amd64) 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker 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 ID: https://cloud.docker.com/ For more examples and ideas, visit: https://docs.docker.com/engine/userguide/
Now we’re are ready to install Rancher.
sudo docker run -d --restart=unless-stopped -p 8080:8080 rancher/server:stable
Wait a few minutes to allow the Rancher UI to boot. Then, open your favorite browser and go to port
8080 on your server.
Be sure to replace
192.0.2.0 with your actual server’s IP address.
Rancher doesn’t configure access control by default, so it is important to set this up immediately, otherwise the UI and API can be accessed by anyone who has your IP.
Hover over the
ADMIN tab, and click
Follow the instructions in the Rancher UI to set up whichever form of access control you prefer.
Everything is now installed and you can begin to configure Rancher. For more in-depth information on configuring and using Rancher, visit their official documentation.
