||
| ## Overview | ||
|
|
||
| This tool has been designed and developed initially by [Edenlab LLC](https://edenlab.io/) as the main CLI | ||
| for managing [Kodjin FHIR Server](https://kodjin.com) on Kubernetes clusters in different environments. | ||
|
|
||
| It is a wrapper around many popular CI/CD and DevOps CLI tools, including: | ||
|
|
||
| - [Helmfile](https://helmfile.readthedocs.io/en/latest/) | ||
| - [Helm](https://helm.sh/) | ||
| - [kubectl](https://kubernetes.io/reference/kubectl/) | ||
| - [SOPS](https://getsops.io/) | ||
| - [Terraform](https://www.terraform.io/) | ||
| - [K3D](https://k3d.io/) | ||
|
|
||
| The main goal of the tool is to simplify ("reduce") management of Kubernetes clusters and releases. | ||
|
|
||
| **RMK** is an abbreviation which stands for "**R**educed **M**anagement for **K**ubernetes". | ||
|
|
||
| ### Advantages | ||
|
|
||
| RMK simplifies the start of any level of complexity of a project using Kubernetes due to the following advantages: | ||
| - **Respects the [GitOPS](https://www.gitops.tech/) approach:** Each Git branch is used as a unique identifier for determining the environment, cluster name, | ||
| set of configurations and other attributes required for setting up the wrapped tools for project management in the Kubernetes environment. | ||
| - **Respects the [GitLabFlow](https://about.gitlab.com/topics/version-control/what-is-gitlab-flow/) workflow**: Supports the standard _develop_, _staging_, _production_ and different ephemeral (e.g, _feature_, _release_) environments. | ||
| - **Provides a transparent project structure with a basic set of configurations**: Allows you to correctly reuse configurations between projects | ||
| and inherit project configurations from other repositories, e.g., establish parent-child ("upstream-downstream") project relationships. | ||
| - **Allows a diverse team to work in the [DevOPS](https://www.atlassian.com/devops) methodology without blocking each other**: Each team or multiple teams | ||
| can develop and release their projects separately, later on the result of their work can be combined in a single project. | ||
| - **Supports versioning of projects in a CI/CD pipeline**: Each project can be versioned and referenced by static or dynamic tags (e.g., [SemVer2](https://semver.org/)), | ||
| which guarantees stable, well-tested and predictable releases. | ||
| - **Integrates with any CI/CD tool easily**: The tool is a self-sufficient binary that strictly follows the [12 factor app](https://12factor.net/) methodology. | ||
| - **Calls the CLI tools directly instead of using their libraries/SDKs**: RMK executes the tools directly in a way that a typical person would do it, | ||
| passing correct sets of CLI arguments and flags to the commands based on a project configuration structure. | ||
| This decouples the updating of RMK itself from the wrapped CLI tools, allowing developers to utilize recent functionality and fixes. | ||
|
|
||
| ### Edenlab LLC use cases | ||
|
|
||
| At [Edenlab LLC](https://edenlab.io/), RMK is used for deploying the [Kodjin FHIR Server](https://kodjin.com). | ||
|
|
||
| A classic Kodjin installation uses 3-level inheritance: | ||
| - **Dependencies (upstream#1)**: Core components like DBs, search engines, caches, load balancers/proxies, operators | ||
| etc. | ||
| - **Kodjin (downstream#1)**: Kodjin FHIR API ([REST](https://en.wikipedia.org/wiki/REST)) | ||
| - **Target installation (downstream#2)**: Products based on Kodjin, such as UI components, user portals and middleware services. | ||
|
|
||
| The additional components used by Kodjin are: | ||
| - **\*.provisioner.infra:** Repositories for Kubernetes cluster provisioning. | ||
| - **helmfile.hooks.infra:** Shell scrips used as [Helmfile hooks](https://helmfile.readthedocs.io/en/latest/#hooks) in | ||
| deps/Kodjin/any other tenant. | ||
| - **core.charts.infra:** Helm charts used by the Kodjin services. | ||
|
|
||
| The examples of Kubernetes providers, to which Kodjin has been installed, are: | ||
| - [Amazon Elastic Kubernetes Service (EKS)](https://aws.amazon.com/eks/) | ||
| - [Open Telekom Cloud - Cloud Container Engine (CCE)](https://www.open-telekom-cloud.com/en/products-services/core-services/cloud-container-engine) | ||
| - [Rancher Kubernetes Platform](https://www.rancher.com/) | ||
| - [Kubermatic Kubernetes Platform (KKP)](https://www.kubermatic.com/) | ||
| - on-premise installations deployed using [Ansible Kubespray](https://github.com/kubernetes-sigs/kubespray) | ||
| - single-machine [K3D](https://k3d.io/) clusters | ||
|
|
||
| #### Related OSS repositories | ||

| - [Azure cluster provider for RMK](https://github.com/edenlabllc/azure.provisioner.infra) | ||
| - [K3D cluster provider for RMK](https://github.com/edenlabllc/k3d.provisioner.infra) | ||
| - [Helmfile hooks](https://github.com/edenlabllc/helmfile.hooks.infra) | ||
|
|
||
| ## Requirements | ||
|
|
||
| Currently, RMK only supports Unix-like operating systems (OS): | ||
| * **OS:** | ||
| * **MacOS**: amd64, arm64 (M1, M2 require [Rosetta](https://support.apple.com/en-us/HT211861)) | ||
| * **Linux**: amd64 | ||
| * **Software:** | ||
| * **Python** >= 3.9 | ||
| * **[AWS CLI](https://aws.amazon.com/cli/)** | ||
| * _For managing local clusters using K3D:_ Version _v5.x.x_ requires [Docker](https://www.docker.com/) => v20.10.5 ([runc](https://github.com/opencontainers/runc) >= v1.0.0-rc93) to work | ||
| properly. | ||
|
|
||
| > If this is your first project repository managed by RMK, ensure that the above tools are specified in the [project.yaml](configuration/project-management/preparation-of-project-repository.md#projectyaml) file. | ||
| ## Installation | ||
|
|
||
| To install RMK, run the self-installer script using the following command: | ||
|
|
||
| ```shell | ||
| curl -sL "https://edenlabllc-rmk.s3.eu-north-1.amazonaws.com/rmk/s3-installer" | bash | ||
| ``` | ||
|
|
||
| Alternatively, you can go directly to https://github.com/edenlabllc/rmk/releases and download the binary. | ||
|
|
||
| As another option, the binary can be [built from source](development-and-release-flow.md#building-from-source). | ||
|
|
||
| ## Update | ||
|
|
||
| ### General update process | ||
|
|
||
| To update RMK to the latest version, run the following command: | ||
|
|
||
| ```shell | ||
| rmk update | ||
| ``` | ||
|
|
||
| ### Update to specific version | ||
|
|
||
| You can update to a specific RMK version to maintain backward compatibility or when updating to the latest version is not possible. | ||
| > This may be necessary due to specific version requirements or when a bug has been detected. | ||
| To update to a specific version, use the following command: | ||
|
|
||
| ```shell | ||
| rmk update --version vX.X.X | ||
| ``` | ||
|
|
||
