This article walks you through the process of installing Coder onto your Kubernetes cluster.


Install the following dependencies if you haven't already:

For production deployments: set up and use an external PostgreSQL instance to store data, including workspace information and session tokens.

Creating the Coder namespace (optional)

We recommend running Coder in a separate namespace; to do so, run

kubectl create namespace coder

Next, change the kubectl context to point to your newly created namespace:

kubectl config set-context --current --namespace=coder

Installing Coder

  1. Add the Coder Helm repo

    helm repo add coder
  2. Install the Helm chart onto your cluster (see the changelog for a list of Coder versions or run helm search repo coder -l)

    helm install coder coder/coder --namespace coder --version=<VERSION>

    Steps 3-5 are optional for non-production deployments.

  3. Get a copy of your Helm config values so that you can modify it; you'll need to modify these values to update your PostgreSQL databases (step 4) and enable dev URLs (step 5):

    a. Create an empty file called values.yaml which will contain your deployment configuration options.

    b. Edit the values.yaml file as needed.

    View the configuration options available in the values.yaml file.

    c. Upgrade/install your Coder deployment with the updated Helm chart (be sure to replace the placeholder value with your Coder version). This must be done whenever you update the Helm chart:

    helm upgrade coder coder/coder --namespace coder --version=<VERSION> --values values.yaml

    If you omit --version, you'll upgrade to the latest version, excluding release candidates (RCs). To include RCs, provide the --devel flag.

    We do not provide documentation for RCs, and you should not use them unless you've been instructed to do so by Coder. You can identify RCs by the presence of -rc in the version number (e.g., 1.16.0-rc.1).

  4. Ensure that you have superuser privileges to your PostgreSQL database. Add the following to your Helm values so that Coder uses your external PostgreSQL databases:

      useDefault: false
      host: HOST_ADDRESS
      port: PORT_NUMBER
      user: YOUR_USER_NAME
      database: YOUR_DATABASE
      passwordSecret: secret-name
      sslMode: require

    To create the passwordSecret, run kubectl create secret generic <NAME> --from-literal="password=UserDefinedPassword" (be sure to replace UserDefinedPassword with your actual password).

    Put a space before the command to prevent it from being saved in your shell history.

    Running this command could potentially expose your database password to other users on your system through /proc. If this is a concern, you can use --from-file=password=/dev/stdin instead of --from-literal=... to enter your password and press Ctrl+D when you're done to submit it.

    You can find/define these values in your PostgreSQL server configuration file.

    For more information, see our guide on setting up a PostgreSQL instance.

  5. Enable dev URL usage. Dev URLs allow users to access the web servers running in your workspace. To enable, provide a wildcard domain and its DNS certificate and update your Helm chart accordingly. This step is optional but recommended.

  6. After you've created the pod, tail the logs to find the randomly generated password for the admin user

    kubectl logs -n coder -l coder.deployment=coderd -c coderd \
     --tail=-1 | grep -A1 -B2 Password

    When this step is done, you will see:

    User:     admin
    Password: kv...k3

    These are the credentials you need to continue setup using Coder's web UI.

If you lose your admin credentials, you can use the admin password reset process to regain access.


At this time, we recommend review Coder's default logging settings. Logs are helpful for monitoring the health of your cluster and troubleshooting, and Coder offers you several options for obtaining these.

Accessing Coder

  1. To access Coder's web UI, you'll need to get its IP address by running the following in the terminal to list the Kubernetes services running:

    kubectl --namespace coder get services

    You'll see a row named coderd with an EXTERNAL-IP value; this is the IP address you need.

  2. In your browser, navigate to the external IP.

  3. Use the admin credentials you obtained in this installation guide's previous step to log in to the Coder platform. If this is the first time you've logged in, Coder will prompt you to change your password.

At this point, you're ready to proceed to configuring Coder.
