| # Setting up Konveyor on a local minikube instance | ||
|
|
||
| The preferred local development for the tackle2-ui is to install the Konveyor | ||
| operator on a minikube instance. When the operator is installed and running, | ||
| the UI development server can attach to it and use the operator's hub api. There | ||
| will also be a running UI instance to work with. | ||
|
|
||
| The setup process follows the general steps: | ||
|
|
||
| - install minikube | ||
| - start minikube with the **dashboard** and **ingress** addons | ||
| - install the operator framework (OLM) | ||
| - install the Konveyor operator | ||
| - optionally add test data | ||
|
|
||
| ## Install and start minikube | ||
|
|
||
| [Minikube](https://github.com/kubernetes/minikube) implements a local Kubernetes cluster | ||
| and is available on macOS, Linux, and Windows. All you need to run minikube is a container | ||
| runtime ([Docker](https://docs.docker.com/engine/install/) or [podman](https://podman.io/docs/installation)) | ||
| or a Virtual Machine environment. | ||
|
|
||
| See the minikube [getting started guide](https://minikube.sigs.k8s.io/docs/start/) for install | ||
| details for your platform. | ||
|
|
||
| By default, Minikube uses a [driver](https://minikube.sigs.k8s.io/docs/drivers/) with 6 GB | ||
| of memory and 2 CPUs. This may not be enough to run all the services, so we need to increase | ||
| the allocated memory. In our experience, 10 GB of memory and 4 CPUs is fine: | ||
|
|
||
| ```sh | ||
| minikube config set memory 10240 | ||
| minikube config set cpus 4 | ||
| ``` | ||
|
|
||
| > [!IMPORTANT] | ||
| > Depending on your driver, administrator access may be required. Common driver choices are | ||
| > Docker for container-based virtualization and KVM for hardware-assisted virtualization on Linux | ||
| > systems. If you're not sure which driver is best for you or if you're encountering compatibility | ||
| > issues, minikube supports auto-selecting a driver based on your system's capabilities and | ||
| > installed software. | ||
| Start minikube with the command: | ||
|
|
||
| ```sh | ||
| minikube start --addons=dashboard --addons=ingress | ||
| ``` | ||
|
|
||
| > [!NOTE] | ||
| > We need to enable the **dashboard** and **ingress** addons. The dashboard addon installs | ||
| > the dashboard service that provides a web UI for the Kubernetes objects. The ingress addon | ||
| > allows us to create Ingress CRs to expose the Tackle UI and Tackle Hub API. | ||
| ## Install OLM | ||
|
|
||
| Since Konveyor is deployed as an operator, the [operator framework](https://operatorframework.io/)'s | ||
| [operator lifecycle manager (OLM)](https://olm.operatorframework.io/) needs to be installed | ||
| on our new minikube instance before installing the Konveyor operator. | ||
|
|
||
| Since the minikube olm addon is disabled until OLM issue | ||
| [2534](https://github.com/operator-framework/operator-lifecycle-manager/issues/2534) | ||
| is resolved we need to install the [OLM manually](https://github.com/operator-framework/operator-lifecycle-manager/releases). | ||
|
|
||
| For version `v0.28.0` (latest version as of 17-May-2024) use the scripts: | ||
|
|
||
| ```sh | ||
| curl -L https://github.com/operator-framework/operator-lifecycle-manager/releases/download/v0.28.0/install.sh -o install.sh | ||
| chmod +x install.sh | ||
| ./install.sh v0.28.0 | ||
| ``` | ||
|
|
||
| ## Install the Konveyor Operator | ||
|
|
||
| There are a few good ways to install the Konveyor operator: | ||
|
|
||
| - Use the script [`hack/setup-operator.sh`](/hack/setup-operator.sh). It is a local variation of | ||
| the script from the operator that applies all CRs needed to install the Konveyor operator and | ||
| setup the Tackle instance. Use of this script is described in the next section. | ||
|
|
||
| - Follow the official instructions for [Installing Konveyor Operator](https://konveyor.github.io/konveyor/installation/#installing-konveyor-operator) | ||
|
|
||
| - Use one of the `hack/install-*` scripts in the [konveyor/operator](https://github.com/konveyor/operator) | ||
| repository. These scripts require `kubectl` and the `operator-sdk`. | ||
|
|
||
| ### Running the setup script | ||
|
|
||
| To run the setup script without cloning the repo, make sure the `kubectl` command (not alias) | ||
| is working and configured for minikube instance, and that the bash shell is available: | ||
|
|
||
| ```sh | ||
| curl https://raw.githubusercontent.com/konveyor/tackle2-ui/main/hack/setup-operator.sh -o setup-operator.sh | ||
| chmod +x setup-operator.sh | ||
| ./setup-operator.sh | ||
| ``` | ||
|
|
||
| You may also run the script directly from you tackle2-ui clone: | ||
|
|
||
| ```sh | ||
| cd tackle2-ui/hack | ||
| ./setup-operator.sh | ||
| ``` | ||
|
|
||
| > [!WARNING] | ||
| > While CRDs are being established, you may see the script output `NotFound` errors. | ||
| > You can safely ignore these. The script will wait and recheck for the CRD again before | ||
| > proceeding. | ||
| The installation is complete when the script outputs "condition met" messages and terminates. | ||
|
|
||
| ### Customizing the setup script | ||
|
|
||
| The setup script provides optional environment variables that may be used to customize the | ||
| images used, settings, and features enabled during the install. | ||
|
|
||
| Configuration environment variable include: | ||
| | variable | default | description | | ||
| | --- | --- | --- | | ||
| | TACKLE*CR | *(empty)\_ | Allows specifying the full Tackle CR | | ||
| | ADDON_ANALYZER_IMAGE | quay.io/konveyor/tackle2-addon-analyzer:latest | image for the ADDON_ANALYZER pod | | ||
| | ANALYZER_CONTAINER_REQUESTS_CPU | 0 | cpu count for the analyzer (0 is no restriction) | | ||
| | ANALYZER_CONTAINER_REQUESTS_MEMORY | 0 | memory size for the analyzer (0 is no restriction) | | ||
| | FEATURE_AUTH_REQUIRED | false | include keycloak SSO in operator deployment | | ||
| | HUB_BUCKET_VOLUME_SIZE | 100Gi | PV claim size for the HUB buckets | | ||
| | HUB_DATABASE_VOLUME_SIZE | 10Gi | PV claim size for the HUB database | | ||
| | HUB_IMAGE | quay.io/konveyor/tackle2-hub:lates | image for the HUB pod | | ||
| | IMAGE_PULL_POLICY | Always | When should images needed by the operator be pulled **link to docs for the pull policy** | | ||
| | NAMESPACE | konveyor-tackle | kubernetes namespace used | | ||
| | OPERATOR_INDEX_IMAGE | quay.io/konveyor/tackle2-operator-index:latest | base operator container image | | ||
| | UI_IMAGE | quay.io/konveyor/tackle2-ui:latest | image for the UI pod | | ||
| | UI_INGRESS_CLASS_NAME | nginx | nginx is the used as the ingress for minikube to access the UI | | ||
|
|
||
| For example, if you wish to run tackle with keycloak authentication enabled, export the following variable before running the install script: | ||
|
|
||
| ```sh | ||
| export FEATURE_AUTH_REQUIRED=true | ||
| ./setup-operator.sh | ||
| ``` | ||
|
|
||
| If the `TACKLE_CR` variable is defined, its contents will be used to create the `Tackle` | ||
| instance in lieu of one built in the script based on the other config variables. For | ||
| example, this will create a Tackle instance with authentication turned on and the UI | ||
| using a specially built test image: | ||
|
|
||
| ```sh | ||
| export TACKLE_CR=$(cat <<EOF | ||
| kind: Tackle | ||
| apiVersion: tackle.konveyor.io/v1alpha1 | ||
| metadata: | ||
| name: tackle | ||
| spec: | ||
| feature_auth_required: true | ||
| ui_image_fqin: quay.io/sdickers/tackle2-ui:test-new-feature | ||
| EOF | ||
| ) | ||
| ./setup-operator.sh | ||
| ``` | ||
|
|
||
| ## Optional Steps... | ||
|
|
||
| ### Considerations for MacOS | ||
|
|
||
| Some core utils used in install and setup scripts may not be available by default on | ||
| a Mac. They are available to install via [Homebrew](https://brew.sh/) as the `coreutils` | ||
| package: | ||
|
|
||
| ```sh | ||
| brew install coreutils | ||
| ``` | ||
|
|
||
| ### Sample data from tackle2-hub | ||
|
|
||
| The [tackle2-hub repo](https://github.com/konveyor/tackle2-hub) has some scripts to add | ||
| basic entities to a Konveyor instance. Using the scripts is a reasonable way to get a | ||
| base setup. Importing that data is [described here](/hack/README.md#adding-a-base-set-of-data-to-an-empty-instance). | ||
|
|
||
| ### Configuring kubectl for minikube | ||
|
|
||
| You will need `kubectl` on your PATH and configured to control minikube in order to proceed. | ||
| There are a few ways to set this up: | ||
|
|
||
| 1. **Install kubectl yourself** | ||
|
|
||
| If you already [have the `kubectl` CLI tool installed](https://kubernetes.io/docs/tasks/tools/#kubectl) | ||
| and available on your PATH, the `minikube start` command should configure it to control the minikube | ||
| cluster. You should see the following message when minikube starts if this worked correctly: | ||
|
|
||
| ``` | ||
| 🏄 Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default | ||
| ``` | ||
|
|
||
| 2. **Use a shell alias for minikube's built-in kubectl** | ||
|
|
||
| Minikube provides its own internal `kubectl` which you can use by running `minikube kubectl --` | ||
| followed by your CLI arguments. If you want to use the built-in `minikube kubectl` as the `kubectl` | ||
| on your shell, you can setup a shell alias. | ||
|
|
||
| The following example shows how to setup an alias for bash on Fedora: | ||
|
|
||
| ```sh | ||
| mkdir -p ~/.bashrc.d | ||
| cat << EOF > ~/.bashrc.d/minikube | ||
| alias kubectl="minikube kubectl --" | ||
| EOF | ||
| source ~/.bashrc | ||
| ``` | ||
| > [!WARNING] | ||
| > The alias will only work for an interactive shell. If you want to use `minikube kubectl --` | ||
| > as the command in scripts, you'll need to use a shim shell script. | ||
| 3. **Use a shim shell script to route kubectl to minikube** | ||
| To be able to use `minikube kubectl --` as the command `kubectl` in general use (interactive | ||
| prompt and in other scripts), a simple shell script can be used. Any location that is in | ||
| the `$PATH` can be used. Installing for all system users can typically be done to `/usr/local/bin`: | ||
| ```sh | ||
| cat << EOF > kubectl.sh | ||
| #! /usr/bin/env bash | ||
| minikube kubectl -- $@ | ||
| EOF | ||
| sudo install -m 777 kubectl.sh /usr/local/bin/kubectl | ||
| ``` | ||
| ## Starting Over | ||
| If at any point your minikube Konveyor operator instance stops working properly, it | ||
| is simple to destroy the environment and rebuild. | ||
| To destroy an existing minikube instance (with Konveyor installed): | ||
| ```sh | ||
| minikube stop | ||
| minikube delete | ||
| ``` | ||
| Rebuild by starting a new instance of minikube and following the rest of the | ||
| install steps in this document. |
