changes in the cluster. It is a sister project for [shell-operator](https://github.com/flant/shell-operator) and is actively used in [Deckhouse Kubernetes Platform](https://github.com/deckhouse/deckhouse) to implement its modules.\n\n# Features\n\n- **Discovery of values** for Helm charts — parameters can be generated, calculated or retrieved from the cluster;\n- **Continuous discovery** — parameters can be changed in response to cluster events;\n- **Controlled Helm execution** — addon-operator monitors the Helm operation to ensure the Helm chart’s successful installation. Coming soon: use kubedog to track deploy status and more;\n- **Custom extra actions before and after running Helm** as well as any other events via the hooks paradigm. See related [shell-operator capabilities](https://github.com/flant/shell-operator/blob/master/HOOKS.md).\n\nAdditionally, addon-operator provides:\n\n- ease of maintenance of Kubernetes clusters: use the tools that Ops are familiar with to build your modules and hooks such as Bash, kubectl, Python, etc;\n- the execution queue of modules and hooks that ensures the launch sequence and repeated execution in case of an error, which *simplifies programming of modules* and ensures *predictable outcome* of their operation;\n- the possibility of *dynamic enabling/disabling* of a module (depending on detected parameters);\n- the ability to tie *conditions of module activation* to the activation of other modules;\n- *the unified ConfigMap* for the configuration of all settings;\n- the ability to run Helm only if parameters have changed. In this case, `helm history` would output only releases with changes;\n- *global hooks* for figuring out parameters and performing actions that affect several dependent modules;\n- off-the-shelf *metrics* for monitoring via Prometheus.\n\n# Documentation\n\nPlease see the [docs](https://flant.github.io/addon-operator/) for more in-depth information and supported features.\n\n# Installation\n\nYou may use a prepared image [flant/addon-operator](https://hub.docker.com/r/flant/addon-operator) to install addon-operator in a cluster. The image comprises a binary `addon-operator` file as well as several required tools: `helm`, `kubectl`, `jq`, `bash`.\n\nThe installation incorporates the image building process with *files of modules and hooks*, applying the necessary RBAC rights and deploying the image in the cluster.\n\n## Examples\n\nTo experiment with modules, hooks, and values we've prepared some [examples](/examples).\n\n[Deckhouse Kubernetes Platform](https://deckhouse.io/) was an initial reason to create addon-operator, thus [its modules](https://github.com/deckhouse/deckhouse/tree/main/modules) might become a vital source of inspiration for implementing your own modules.\n\nSharing your examples of using addon-operator is much appreciated. Please, use the [relevant Discussions section](https://github.com/flant/addon-operator/discussions/categories/show-and-tell) for that.\n\n# What's next?\n\nExplore [shell-operator](https://github.com/flant/shell-operator) documentation, especially its [hooks](https://github.com/flant/shell-operator/blob/main/docs/src/HOOKS.md) section.\n\n# Community\n\nPlease feel free to reach developers/maintainers and users via [GitHub Discussions](https://github.com/flant/addon-operator/discussions) for any questions regarding addon-operator.\n\nYou're also welcome to follow [@flant_com](https://twitter.com/flant_com) to stay informed about all our Open Source initiatives.\n\n# License\n\nApache License 2.0, see [LICENSE](LICENSE).\n","funding_links":[],"categories":["Go","Operators"],"sub_categories":["[Jenkins](#jenkins)"],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fflant%2Faddon-operator","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fflant%2Faddon-operator","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fflant%2Faddon-operator/lists"}
