Coder has open-sourced a new remote development platform 🥳 Check it out at coder/coder on GitHub.

Nightly releases

Coder offers a public nightly release Helm repository that's updated most weeknights at 12:00 AM Central. Nightly releases may contain unreleased hotfixes and new features that haven't been documented.

All customers are free to use the nightly release for their deployments. However, be aware that breaking bugs will sometimes get shipped via our nightly release pipeline despite both our manual and automated testing processes. Furthermore, new features that we make available via nightly releases may not be up to the standard of the mature features we've fully released. These features may also have inconsistent UI or unimplemented controls.

Occasionally, we will retract a nightly release from the repository if we find that it causes data loss or includes major bugs/instability issues. This retraction will not fix your deployment automatically; you must revert to a backup manually.

We recommend you backup your database before proceeding with any of the steps on this page.

Obtaining the nightly releases

We store nightly releases in this Helm repository. We store images in a publicly accessible gcr.io repository.

Nightly release listing

The list of nightly releases is maintained in the Helm repository's index. We automatically prune old nightly releases, so you'll see a maximum of 100 entries. The easiest way to view the index is to obtain it using curl:

$ curl https://helm-nightly.coder.com/index.yaml

apiVersion: v1
entries:
  coder:
  - apiVersion: v2
    created: "2020-09-25T00:02:52.661335099-05:00"

    name: coder
    type: application
    urls:
    - https://helm-nightly.coder.com/coder-1.11.0-90-gb0e792c7e-20200924.tgz
        version: 1.11.0-90-gb0e792c7e-20200924
  - ...
generated: "2020-09-28T00:02:05.129533118-05:00"

The topmost version under entries.coder is the most recent version. In most cases, this is the version you'll want to use.

Each nightly version contains a date at the end in YYYYMMDD format. This version will also be displayed in the Coder UI; when contacting support, it's crucial that you provide the entire version string to us.

For automation purposes, you can use the following one-liner to get the current nightly version:

# Requires curl, yq, jq
$ curl -sS https://helm-nightly.coder.com/index.yaml \
| yq r --tojson - \
| jq -r "[.entries.coder | sort_by(.created) | reverse][0][0].version"

1.11.0-108-g01693c0e2-20200926

Installing a nightly release via Helm

  1. Add the Helm repo (if you haven't already):

    $ helm repo add coder-nightly https://helm-nightly.coder.com
    "coder-nightly" has been added to your repositories
    
  2. Install a specific version to the coder namespace (be sure to backup your database before running the following command):

      $ helm upgrade --namespace coder coder coder-nightly/coder \
      --version <VERSION> --atomic --install
    
      Release "coder" has been upgraded. Happy Helming!
      NAME: coder
      LAST DEPLOYED: Mon Sep 28 16:38:36 2020
      NAMESPACE: coder
      STATUS: deployed
      REVISION: 2
      TEST SUITE: None
    

    The --atomic flag instructs Helm to automatically downgrade if the nightly release isn't ready within the default timeout of 5 minutes. This automatic downgrade on failure is safe and shouldn't require you to manually downgrade to your database backup if it occurs.

Downgrading to a standard release

Downgrading is not something we support at this time. If you need to downgrade, you must revert to the database backup you made before installing the nightly release.

If your currently installed nightly version is sufficiently older than a standard release (i.e., more than a week older), consider upgrading from the nightly release to the standard release.
