Table 1. Prerequisites

Requirement

Version

Ansible

>= v2.6

Openshift Container Platform

>= v3.11

Openshift CLI (OC)

>= v3.11

⚠️
  • SSH Access to Openshift master(s)

  • Cluster administrator permissions

Installation Steps

RHPDS

The following steps will provide information on how to install Integreatly on an RHPDS Openshift cluster.

SSH to the master host and become root

ssh -i /path/ocpkey.pem [email protected]

sudo -i

Clone installation GIT repository on the master host

git clone https://github.com/integr8ly/installation.git

Create GitHub OAuth to enable GitHub authorization [OPTIONAL]

  1. Login into GitHub

  2. Go to Settings >> Developer Settings >> New OAuth App.

    GitHub OAuth App
  3. Add the following fields values

    Table 2. Fields values descriptions

    Field

    Value

    Application Name

    Any value

    Home Page URL

    http://localhost

    Authorization callback URL

    http://localhost

    The callback URL is a placeholder for now and will be changed after the installation playbook is finished.
  4. Click on Register Application

  5. The values found in GitHub OAuth App, Client ID and Client Secret, will be needed in the next step to install Integreatly.

GitHub OAuth App Fields

Run the installation playbook

All products can be installed using the install.yml playbook located in the playbooks/ directory.

Before running the installer, please consider the following variables:

Table 3. Install playbook variables

Variable

Description

eval_self_signed_certs

Whether the OpenShift cluster uses self-signed certs or not. Defaults to false

github_client_id

GitHub OAuth client ID to enable GitHub authorization for Launcher. If not defined, GitHub authorization for Launcher will be disabled

github_client_secret

GitHub OAuth client secret to enable GitHub authorization for Launcher. If not defined, GitHub authorization for Launcher will be disabled

prerequisites_install

Boolean var that skips the installation of system wide tools/packages that are required by the installer if set to false (needs to be set to false when running the installer in a linux container). Defaults to true.

heimdall_pull_secret_token

Heimdall pull secret token

Some products can be excluded from the install by setting a var. For example, setting gitea=false will not install gitea. The flags for installing specific products can be found in the manifest.yaml file

ℹ️
Installation of individual products will not be a supported installation method with this repo. You can however write your own playbook to execute specific roles & tasks as needed.

By default Mobile Developer Services will not be installed. In order to install these services, consider the following variables.

Table 4. Install Mobile Developer Services

Variable

Description

Default Value

ups

Whether Mobile Unified Push Server will be installed or not

true

datasync

Whether DataSync components will be installed or not

true

The installation can be run using the following command:

ℹ️
If installing v1.5.2 or any prior release set the inventory file to inventories/hosts.template rather than inventories/pds.template as shown below
ansible-playbook -i inventories/pds.template playbooks/install.yml -e github_client_id=<your_client-id> -e github_client_secret=<your_client_secret>

The following flag can be used if self signed certs are used.

-e eval_self_signed_certs=true

To enable Heimdall you will need a valid pull secret token to access the registry, you can retrieve these from https://access.redhat.com/terms-based-registry/#/token/-heimdall/openshift-secret

Click on view its contents. Use the entry at data.dockerconfigjson to replace <your_secret_token> below.

-e heimdall_pull_secret_token=<your_secret-token>
💡
The following command installs Integreatly without GitHub authorization for Launcher.
 ansible-playbook -i inventories/pds.template playbooks/install.yml

Add the generated Authorization callback URL to GitHub OAuth

Replace the authorization callback URL previously containing a temporary localhost value with the output of the installation seen below.

TASK [debug] *************************************************************************************************************************************************************************************************
ok: [127.0.0.1] => {
    "msg": "All services have been provisioned successfully. Please add 'https://launcher-sso-launcher.apps.example.open.redhat.com/auth/realms/launcher_realm/broker/github/endpoint' as the Authorization callback URL of your GitHub OAuth Application."
}

NOTE: Requires an existing s3 secret s3-credentials in the backup namespace.

Sample command:

Uninstalling Integreatly

Run the uninstall.yml playbook from the root of the repository:

ℹ️
If installing v1.5.2 or any prior release set the inventory file to inventories/hosts.template rather than inventories/pds.template as shown below
ansible-playbook -i inventories/pds.template playbooks/uninstall.yml

By default this will delete all user-created namespaces as well, if you wish to keep these namespaces then add the following flag:

-e keep_namespaces=true

Troubleshooting

Message "You need to install \"jmespath\" prior to running json_query filter" is shown when the installation fails

The issue means that python version used by Ansible has not this required module. In order to fix it is required to install the missing module. Following the command to install it via pip.

$ pip install jmespath
ℹ️
The module need to be installed in the same version of python used by Ansible. Use the command $ ansible --version to check this path.
Message "jsonpointer module is not available" is shown when the installation fails

The issue means that python version used by Ansible has not this required module. In order to fix it is required to install the missing module. Following the command to install it via pip.

$ pip install jsonpointer

Also, you might need to use the varible ansible_python_interpreter in the inventory file being used to fix it, for example:

[local:vars]
ansible_connection=local
ansible_python_interpreter=python
💡
The module need to be installed in the same version of python used by Ansible. Use the command $ ansible --version to check this path.

Self Signed Certs with Che

If your cluster is using a self signed (non CA) certificate, there are a couple of things that needs to be noted.

  • Che will only allow the creation of one workspace when self signed certificates are used.

  • When a workspace is created, the following errors may appear on the workspace:

Connection failed with terminal
Some error happened with terminal WebSocket connection
Failed to import project
  • In order to solve these issues, you will need to accept the certs for all the routes that was created for that workspace. These routes are listed in the workspace deployment within the Che namespace.
