![]() Once merged to the master branch, the chart will be packaged and released to Helm’s default repository and available for users to install.Once tested and reviewed, the PR will be merged. Submit a Pull Request to the Kubernetes Charts repo.Most charts requiring this today are using dynamic volume provisioning to abstract away underlying storage details from the user which allows a single configuration to work against Kubernetes installations. If the application requires persistent storage, the developer adds a mechanism to store the data such that pod restarts do not lose data.This file generally points out the next steps for the user to connect to or use the application. Once the application installs properly and the values customize the deployment appropriately, the developer adds a NOTES.txt file that is shown as soon as the user installs.A README is written to help describe the application and its parameterized values.This can be seen as the API between chart devs and chart users. Developer provides parameters via the values.yaml file allowing users to customize their deployment.The following applications are now available: Stable repository For more information on the repository structure and requirements for being in stable, have a look at this section in the README. The incubator folder provides a place for charts to be submitted and iterated on until they’re ready for promotion to stable at which time they will automatically be pushed out to the default repository. The stable folder hosts those applications which meet minimum requirements such as proper documentation and inclusion of only Beta or higher Kubernetes resources. There are two main folders where charts reside. ![]() The home for these Charts is the Kubernetes Charts repository which provides continuous integration for pull requests, as well as automated releases of Charts in the master branch. Helm is the package manager (analogous to yum and apt) and Charts are packages (analogous to debs and rpms). Helm allows users to easily templatize their Kubernetes manifests and provide a set of configuration parameters that allows users to customize their deployment. These packages are being created as Helm Charts and can be installed using the Helm tool. As part of the Special Interest Group Apps ( SIG Apps) work for the Kubernetes 1.4 release, we began to provide a home for these Kubernetes deployable applications that provides continuous releases of well documented and user friendly packages. ![]() In this case, we’re not creating Yet Another Place for Applications, rather promoting an existing one as the canonical location. So what do you do when there are too many places for things to be found? While these different locations provided guidance, it was not always formalized or consistent such that users could leverage similar installation procedures across different applications. Once that application is deployed users can link it to their existing systems or leverage their functionality to solve their pain points.įor best practices on how these applications should be configured, users could look at the many resources available such as: the examples folder in the Kubernetes repository, the Kubernetes contrib repository, the Helm Charts repository, and the Bitnami Charts repository. These types of applications are usually not ones that are developed and iterated on by end users, but rather their configuration is customized to fit a specific use case. ![]() There are some very common applications that users regularly look for guidance on deploying, such as databases, CI tools, and content management systems. This usually involves crafting a few different Kubernetes resource definitions that configure the application runtime, as well as defining the mechanism that users and other apps leverage to communicate with the application. There are thousands of people and companies packaging their applications for deployment on Kubernetes.
