Docker

Coder with Docker has the following advantages:

• Simple installation (everything is on a single box)
• Workspace images are easily configured
• Workspaces share resources for burst operations

Requirements

• A single MacOS or Linux box
• A running Docker daemon

Instructions

1. Install and launch Coder

   You may use CODER_ACCESS_URL=http://localhost:7080 since we're using local Docker workspaces exclusively. The rest of the guide will assume that this is your access URL.

   coder server -a $CODER_ACCESS_URL
   

2. Run coder login http://localhost:7080 in a new terminal and follow the interactive instructions to create your user.

3. Pull the example template:

   echo "docker" | coder templates init
   cd docker
   # You should see a `main.tf` file in this directory
   

4. Open up main.tf in your preferred editor to edit the images

   You can skip this step if you're fine with our default, generic OS images.

   Search for the following section in main.tf:

   ...
   variable "docker_image" {
    description = "Which Docker image would you like to use for your workspace?"
    # The codercom/enterprise-* images are only built for amd64
    default = "codercom/enterprise-base:ubuntu"
    validation {
        condition     = contains(["codercom/enterprise-base:ubuntu", "codercom/enterprise-node:ubuntu",
                                "codercom/enterprise-intellij:ubuntu", "codercom/enterprise-golang:ubuntu"], var.docker_image)
        error_message = "Invalid Docker image!"
    }
   }
   ...
   

   And edit the strings in condition = contains([...]) and default = ... with your preferred images.

5. Push up the template to Coder with coder templates create

6. Open the dashboard in your browser (http://localhost:7080) to create your first workspace:

   

   Then navigate to Templates > docker > Create workspace

   

   Now wait a few moments for the workspace to build... After the first build the image is cached and subsequent builds will take a few seconds.

7. All done!

   

   Open up a web application or SSH in.
