Chapter 2. Installing Dev Spaces
This section contains instructions to install Red Hat OpenShift Dev Spaces.
You can deploy only one instance of OpenShift Dev Spaces per cluster.
2.1. Installing the dsc management tool
You can install dsc
, the Red Hat OpenShift Dev Spaces command-line management tool, on Microsoft Windows, Apple MacOS, and Linux. With dsc
, you can perform operations the OpenShift Dev Spaces server such as starting, stopping, updating, and deleting the server.
Prerequisites
Linux or macOS.
NoteFor installing
dsc
on Windows, see the following pages:
Procedure
-
Download the archive from https://developers.redhat.com/products/openshift-dev-spaces/download to a directory such as
$HOME
. -
Run
tar xvzf
on the archive to extract the/dsc
directory. -
Add the extracted
/dsc/bin
subdirectory to$PATH
.
Verification
Run
dsc
to view information about it.$ dsc

2.2. Installing Dev Spaces on OpenShift using CLI
You can install OpenShift Dev Spaces on OpenShift.
Prerequisites
- OpenShift Container Platform
-
An active
oc
session with administrative permissions to the OpenShift cluster. See Getting started with the OpenShift CLI. -
dsc
. See: Section 2.1, “Installing the dsc management tool”.
Procedure
Optional: If you previously deployed OpenShift Dev Spaces on this OpenShift cluster, ensure that the previous OpenShift Dev Spaces instance is removed:
$ dsc server:delete
Create the OpenShift Dev Spaces instance:
$ dsc server:deploy --platform openshift
Verification steps
Verify the OpenShift Dev Spaces instance status:
$ dsc server:status
Navigate to the OpenShift Dev Spaces cluster instance:
$ dsc dashboard:open
2.3. Installing Dev Spaces on OpenShift using the web console
This section describes how to install OpenShift Dev Spaces using the OpenShift web console. Consider Section 2.2, “Installing Dev Spaces on OpenShift using CLI” instead.
Prerequisites
- An OpenShift web console session by a cluster administrator. See Accessing the web console.
Procedure
Optional: If you previously deployed OpenShift Dev Spaces on this OpenShift cluster, ensure that the previous OpenShift Dev Spaces instance is removed:
$ dsc server:delete
- Install the Red Hat OpenShift Dev Spaces Operator. See Installing from OperatorHub using the web console.
Create the
openshift-devspaces
project in OpenShift as follows:oc create namespace openshift-devspaces
-
In the Administrator view of the OpenShift web console, go to
. -
In the YAML view, replace
namespace: openshift-operators
withnamespace: openshift-devspaces
. - Select Create. See Creating applications from installed Operators.
Verification
- To verify that the OpenShift Dev Spaces instance has installed correctly, navigate to the Dev Spaces Cluster tab of the Operator details page. The Red Hat OpenShift Dev Spaces instance Specification page displays the list of Red Hat OpenShift Dev Spaces instances and their status.
-
Click devspaces
CheCluster
and navigate to the Details tab. See the content of the following fields:
-
The Message field contains error messages. The expected content is
None
. - The Red Hat OpenShift Dev Spaces URL field contains the URL of the Red Hat OpenShift Dev Spaces instance. The URL appears when the deployment finishes successfully.
-
The Message field contains error messages. The expected content is
- Navigate to the Resources tab. View the list of resources assigned to the OpenShift Dev Spaces deployment and their status.
2.4. Installing Dev Spaces in a restricted environment
On an OpenShift cluster operating in a restricted network, public resources are not available.
However, deploying OpenShift Dev Spaces and running workspaces requires the following public resources:
- Operator catalog
- Container images
- Sample projects
To make these resources available, you can replace them with their copy in a registry accessible by the OpenShift cluster.
Prerequisites
- The OpenShift cluster has at least 64 GB of disk space.
- The OpenShift cluster is ready to operate on a restricted network, and the OpenShift control plane has access to the public internet. See About disconnected installation mirroring and Using Operator Lifecycle Manager on restricted networks.
-
An active
oc
session with administrative permissions to the OpenShift cluster. See Getting started with the OpenShift CLI. -
An active
oc registry
session to theregistry.redhat.io
Red Hat Ecosystem Catalog. See: Red Hat Container Registry authentication.
-
opm
. See Installing theopm
CLI. -
jq
. See Downloadingjq
. -
podman
. See Installing Podman. -
An active
skopeo
session with administrative access to the <my_registry> registry. See Installing Skopeo, Authenticating to a registry, and Mirroring images for a disconnected installation. -
dsc
for OpenShift Dev Spaces version 3.4. See Section 2.1, “Installing the dsc management tool”.
Procedure
Download and execute the mirroring script to install a custom Operator catalog and mirror the related images: prepare-restricted-environment.sh.
$ bash prepare-restricted-environment.sh \ --ocp_ver "4.11" \ --devworkspace_operator_index "registry.redhat.io/redhat/redhat-operator-index:v4.10" \ --devworkspace_operator_version "v0.18.1" \ --prod_operator_index "registry.redhat.io/redhat/redhat-operator-index:v4.10" \ --prod_operator_package_name "devspaces-operator" \ --prod_operator_version "v3.4.0" \ --my_registry "<my_registry>" \ --my_catalog "<my_catalog>"
Install OpenShift Dev Spaces with the configuration set in the
che-operator-cr-patch.yaml
during the previous step:$ dsc server:deploy --platform=openshift \ --che-operator-cr-patch-yaml=che-operator-cr-patch.yaml
- Allow incoming traffic from the OpenShift Dev Spaces namespace to all Pods in the user projects. See: Section 3.7.1, “Configuring network policies”.
