Local preview

Coder is typically deployed onto Kubernetes cluster, but if you would like to set up a lightweight preview deployment, you can do so locally using using Docker and kind.

Coder currently supports local preview only on workstations running macOS or Linux.

Prerequisites

Before proceeding, please make sure that you have the following installed:

1. Docker
2. helm
3. kind
4. kubectl

Limitations

CVMs

The local preview supports CVMs if you meet the following requirements (if you choose not to try out CVMs, these requirements do not apply):

1. Your Linux hosts must be running Linux Kernel 5 and above.

2. You must have the linux-headers package corresponding to your Kernel version installed. You should see the following folders all corresponding to your Kernel version:

   $ uname -r
   5.11.4-arch1-1
   $ ls /usr/lib/modules
   5.11.4-arch1-1
   $ ls /usr/src/
   linux  linux-headers-5.11.4-arch1-1
   

3. Docker Desktop for Mac must use version 2.5.0.1. This specific version is required because of a recent downgrade to Linux Kernel 4.9 due to a bug.

Dev URLs

Currently, the local preview doesn't support Dev URLs. Instead, you can use tools like ngrok to preview webpages from inside an environment.

We are working on bringing Dev URL support to local previews in later releases.

Installing Coder

To install Coder, run:

curl -fsSL https://coder.com/try.sh | PORT="8080" sh -s --

Note: you can edit the value of PORT to control where the Coder dashboard will be available.

When the installation process completes, you'll see the URL and login credentials you need to access Coder:

You can now access Coder at

    http://localhost:8080

You can tear down the deployment with

    curl -fsSL https://coder.com/try.sh | sh -s -- down

Platform credentials
User:     admin
Password: yfu...yu2

Visit the URL, and log in using the provided credentials. The platform is automatically configured for you, so there's no first-time setup to do.

Removing Coder

To remove the local Coder deployment, run:

curl -fsSL https://coder.com/try.sh | sh -s -- down

Because Coder runs inside Docker, you should have nothing left on your machine after tear down.
