It supports issuing certificates from a variety of sources, including Let's Encrypt (ACME), HashiCorp Vault, and CyberArk Certificate Manager, as well as local in-cluster issuance. cert-manager also ensures certificates remain valid and up to date, attempting to renew certificates at an appropriate time before expiry to reduce the risk of outages and remove toil.  ## Documentation Documentation for cert-manager can be found at [cert-manager.io](https://cert-manager.io/docs/). For the common use-case of automatically issuing TLS certificates for Ingress resources, see the [cert-manager nginx-ingress quick start guide](https://cert-manager.io/docs/tutorials/acme/nginx-ingress/). For a more comprehensive guide to issuing your first certificate, see our [getting started guide](https://cert-manager.io/docs/getting-started/). ### Installation [Installation](https://cert-manager.io/docs/installation/) is documented on the website, with a variety of supported methods. ## Developing cert-manager We actively welcome contributions and we support both Linux and macOS environments for development. Different platforms have different requirements; we document everything on our [Building cert-manager](https://cert-manager.io/docs/contributing/building/) website page. Note in particular that macOS has several extra requirements, to ensure that modern tools are installed and available. Read the page before getting started! ## Troubleshooting If you encounter any issues whilst using cert-manager, we have a number of ways to get help: - A [troubleshooting guide](https://cert-manager.io/docs/faq/troubleshooting/) on our website. - Our official [Kubernetes Slack channel](https://cert-manager.io/docs/contributing/#slack) - the quickest way to ask! ([#cert-manager](https://kubernetes.slack.com/messages/cert-manager) and [#cert-manager-dev](https://kubernetes.slack.com/messages/cert-manager-dev)) - [Searching for an existing issue](https://github.com/cert-manager/cert-manager/issues). If you believe you've found a bug and cannot find an existing issue, feel free to [open a new issue](https://github.com/cert-manager/cert-manager/issues)! Be sure to include as much information as you can about your environment. ## Community The [`cert-manager-dev` Google Group](https://groups.google.com/forum/#!forum/cert-manager-dev) is used for project wide announcements and development coordination. Anybody with a Google account can join the group by visiting the group and clicking "Join Group". ### Meetings We have several public meetings which any member of our Google Group is more than welcome to join! Check out the details on [our website](https://cert-manager.io/docs/contributing/#meetings). Feel free to drop in and ask questions, chat with us or just to say hi! ## Contributing We welcome pull requests with open arms! There's a lot of work to do here, and we're especially concerned with ensuring the longevity and reliability of the project. The [contributing guide](https://cert-manager.io/docs/contributing/) will help you get started. ## Coding Conventions Code style guidelines are documented on the [coding conventions](https://cert-manager.io/docs/contributing/coding-conventions/) page of the cert-manager website. Please try to follow those guidelines if you're submitting a pull request for cert-manager. ## Importing cert-manager as a Module ⚠️ Please note that cert-manager **does not** currently provide a Go module compatibility guarantee. That means that **most code under `pkg/` is subject to change in a breaking way**, even between minor or patch releases and even if the code is currently publicly exported. The lack of a Go module compatibility guarantee does not affect API version guarantees under the [Kubernetes Deprecation Policy](https://kubernetes.io/docs/reference/using-api/deprecation-policy/). For more details see [Importing cert-manager in Go](https://cert-manager.io/docs/contributing/importing/) on the cert-manager website. The import path for cert-manager versions 1.8 and later is `github.com/cert-manager/cert-manager`. For all versions of cert-manager before 1.8, including minor and patch releases, the import path is `github.com/jetstack/cert-manager`. ## Security Reporting Security is the number one priority for cert-manager. If you think you've found a security vulnerability, we'd love to hear from you. Follow the instructions in [SECURITY.md](./SECURITY.md) to make a report. ## Changelog [Every release](https://github.com/cert-manager/cert-manager/releases) on GitHub has a changelog, and we also publish release notes on [the website](https://cert-manager.io/docs/release-notes/). ## History cert-manager is loosely based upon the work of [kube-lego](https://github.com/jetstack/kube-lego) and has borrowed some wisdom from other similar projects such as [kube-cert-manager](https://github.com/PalmStoneGames/kube-cert-manager). _{^{Logo design by [Zoe Paterson](https://zoepatersonmedia.com)}} ", Assign "at most 3 tags" to the expected json: {"id":"2712","tags":[]} "only from the tags list I provide: []" returns me the "expected json"
