# GitOps Based Installation

The document is primarily intended to be used for standard ISD GitOps based installation.

## Infrastructure and Laptop requirements

Before you start, it might be helpful to go through these documents: 

* The infrastructure required for a non-prod installation can be found [**here**](https://docs.opsmx.com/release-history/previous-releases/isd-4.0/operator-manual/installation-and-configuration/isd-on-prem-pov-infrastructure-requirements)
* The infrastructure required for a Production Setup can be found [**here**](https://docs.opsmx.com/release-history/previous-releases/isd-4.0/operator-manual/installation-and-configuration/isd-on-prem-production-infrastructure-requirements)
* Basic requirements of a laptop and Kubernetes cluster can be found [**here**](https://docs.opsmx.com/release-history/previous-releases/isd-4.0/operator-manual/installation-and-configuration/environment-setup-for-opsmx-isd)**.**

### Create your git-repo

ISD stores all the configuration in a repo, typically a **git repo,** though bitbucket, S3, and others are supported.

1. Create an empty-repo (called the "gitops-repo" in the document), "main" branch should be the default, and clone it locally.

2. Clone <https://github.com/OpsMx/standard-isd-gitops>, selecting the appropriate branch:\
   `git clone https://github.com/OpsMx/standard-isd-gitops -b 4.0.4.1`

3. Copy contents of the standard-isd-repo to the gitops-repo created above using:\
   `cp -r standard-isd-gitops/* gitops-repo` # Replace "gitops-repo" with your repo-name and cd to the gitops-repo e.g. `cd gitops-repo.`\
   \
   **Specify inputs**\
   Specify the inputs based on your environment and git-repo. The installation process requires inputs such as the application version, git-repo details, etc.

4. In the gitops-repo cloned to disk and edit `install/inputcm.yaml`. This should be updated, at a **minimum**, with gitrepo and username.

5. **Update Values.yaml as required**, specifically: At **minimum** the ISD URL and gitops-repo details in the spinnaker.gitopsHalyard section must be updated. Full values.yaml is available at the following link: [ **https://github.com/OpsMx/enterprise-spinnaker/tree/v4.0.4/charts/oes**](https://github.com/OpsMx/enterprise-spinnaker/tree/v4.0.4/charts/oes)[<br>](https://github.com/OpsMx/enterprise-spinnaker/tree/v4.0.4/charts/oes)

   <div data-gb-custom-block data-tag="hint" data-style="info" class="hint hint-info"><p><strong>NOTE</strong>: We recommend that we start with the defaults, updating just the URL and gitopsHalyard details and gradually adding SSO, external DBs, etc. while updating the installed instance.</p></div>

6. Edit namespace in the install/services.yaml file, if changed from default (that is,"opsmx-isd")

7. Push all changes in the gitops-repo to git (E.g `git add -A; git commit -m"my changes";git push`).&#x20;

8. Create namespace, a configmap for inputs, and a service account as follows \[Edit namespace (that is, opsmx-isd) as appropriate]:

   ```
   kubectl create ns opsmx-isd
   kubectl -n opsmx-isd apply -f install/inputcm.yaml
   kubectl -n opsmx-isd apply -f install/serviceaccount.yaml
   ```

   \
   **Create secrets**

   ISD supports multiple secret managers for storing secrets such as DB passwords, SSO authentication details, and so on. Using Kubernetes secrets is the default.

9. Create the following secrets. The default values are handled by the installer, except for gittoken. If you are using External SSO, DBs, etc. you might want to change them. Else, best to leave them at the defaults:

   `kubectl -n opsmx-isd create secret generic gittoken --from-literal=gittoken=PUT_YOUR_GITTOKEN_HERE`

   ####

   #### Optional

   In case we want to change these, please enter the correct values and create the secrets

   <pre data-overflow="wrap"><code>kubectl -n opsmx-isd create secret generic ldapconfigpassword --from-literal ldapconfigpassword=PUT_YOUR_SECRET_HERE
   kubectl -n opsmx-isd create secret generic ldappassword --from-literal ldappassword=PUT_YOUR_SECRET_HERE
   kubectl -n opsmx-isd create secret generic miniopassword --from-literal miniopassword=PUT_YOUR_SECRET_HERE
   kubectl -n opsmx-isd create secret generic redispassword --from-literal redispassword=PUT_YOUR_SECRET_HERE
   kubectl -n opsmx-isd create secret generic saporpassword --from-literal saporpassword=PUT_YOUR_SECRET_HERE
   kubectl -n opsmx-isd create secret generic rabbitmqpassword --from-literal rabbitmqpassword=PUT_YOUR_SECRET_HERE
   kubectl -n opsmx-isd create secret generic keystorepassword --from-literal keystorepassword=PUT_YOUR_SECRET_HERE
   </code></pre>

   \
   **Start the installation**

   The installation is done by a Kubernetes job that processes the secrets, generates YAMLs, stores them into the git-repo and creates the objects in Kubernetes.

10. &#x20;Installation ISD by executing this command:\
    `kubectl -n opsmx-isd apply -f install/ISD-Install-Job.yaml`

    \
    **Monitor the installation process**

11. Wait for all pods to stabilize (about 10-20 min, depending on your cluster load). The "oes-config" in completed status indicates completion of the installation process. Check the status using the following comment: `kubectl -n opsmx-isd get po -w`

    \
    **Note:** If the pod starting with isd-install-\* errors out, please check the logs as follows, and replace the pod-name correctly:

    ```yaml
    kubectl -n opsmx-isd logs isd-install-tjzlx -c get-secrets
    kubectl -n opsmx-isd logs isd-install-tjzlx -c git-clone
    kubectl -n opsmx-isd logs isd-install-tjzlx -c apply-yamls
    ```

    \
    **Note**: It is normal for some pods, specifically the oes-ui pod to crash a few times before running. However, if the isd-spinnaker-halyard-0 pod crashes or errors out, please check the logs of the "create-halyard-local" init container using this command:

    `kubectl -n opsmx-isd logs isd-spinnaker-halyard-0 -c create-halyard-local`

    \
    **Check the installation**

12. Access ISD using the URL specified in the values.yaml in step 5 in a browser such as Chrome.

13. Login to the ISD instance by using the credentials listed below:

    * **User Name**: admin
    * **Password**: Execute the following command to retrieve the password<br>

      <pre data-overflow="wrap"><code>kubectl -n opsmx-isd get secret isd-openldap -o jsonpath='{.data.LDAP_ADMIN_PASSWORD}'| base64 -d
      </code></pre>

      \
      In case "base64 command not found": Please execute the below command. <br>

      <pre data-overflow="wrap"><code>kubectl -n opsmx-isd get secret isd-openldap -o jsonpath='{.data.LDAP_ADMIN_PASSWORD}'
      </code></pre>

      After executing the above command, copy the output and decode it using any online decoding site such as [**https://www.base64decode.org/**](https://www.base64decode.org/).

    **Switch from OpenLDAP to Saml**

14. Inorder to Install/Upgrade you can use the saml-values.yaml file. Refer [Instructions to Update the Parameters in value.yaml ](https://docs.opsmx.com/operator-manual/installation-and-configuration/standard-installation/isd-v4.0.4.1/instructions-to-update-the-parameters-in-value.yaml)for updating to SAML from OpenLDAP.

    * Move the old values.yaml to openldap-values.yaml and saml-values.yaml to values.yaml

    **NOTE**: Make sure values.yaml has saml configuration
