IntelliJ IDEA 2021.1 brings some updates to Kubernetes and Docker, making development more convenient. In this blog post, we will describe them in detail.

Governors
Quickly delete resources
Now you can delete all cluster resources in the current context directly from the editor-just click the run icon in the gutter and select delete .
Support Kustomize 3.7.0 components
We have added support for the new Kustomize 3.7.0 component. You can select this new option from the Kustomize version drop-down list in "Settings/Preference | Languages & Frameworks | Kubernetes".
Support kind: List
If you want to use the content returned by the'kubectl get <resource type> -o yaml' command, or if you want to apply the resource list, I will tell you a good news: your IDE now supports kind: List!
In each resource in the list, you can rename the tag, use code assist and navigate through the groove icon. You can also convert a list into a multi-document YAML file by clicking Alt+Enter and selecting the relevant intent operation, and vice versa.
Non-default values for Helm items
Helm chart is a set of parameterized Kubernetes resource descriptions. By default, the parameters are specified in values.yaml, but Helm allows any number of non-default Values files to be used. Before v2021.1, the default values.yaml was the only option for code insight and running Helm commands.
In IntelliJ IDEA 2021.1, we can already use custom Values files. Now, the IDE treats all files with "values" in their names as values files.
To configure which value files the chart template will use, select Configure Helm Parameters or call Helm Lint or Helm Template from the context menu. A dialog box will open where you can add the required value file. If you want to skip this dialog when executing the Helm command, please check the box at the bottom.
You can also manually add values by pasting in the additional value area.
Docker
Improved run/debug configuration
We have modified your run/debug configuration dialog box to make it more tidy and can be adjusted according to your needs. To add all necessary build options, click "Modify Options"; to add run options, click "Modify". The IDE will now verify each option to make sure it is compatible.
For Docker Compose, we support all existing options, including the option to declare environment variable files (.env).
For Dockerfile, you don't have to remember all the running commands, because the code completion can be done in the " Run Options" field.
For images , you can use code completion to enter the image name in the image ID or name field.
BuildKit support
We have added experimental support for BuildKit, which greatly increases the speed of building projects. You can activate this option in the run/debug configuration by clicking Modify option and then selecting Enable BuildKit (experimental) .
Building named stages separately from the entire multi-stage Dockerfile is now easier and faster. Just click the hammer icon next to the stage name, and the IDE will use BuildKit to build the image. If you add the "Run" section to the "Run/Debug Configuration", the icon will change. When you click on it, you will not only build an image, but also run a container.
UI enhancement in multi-stage Dockerfile
If you use multiple FROM statements in a Dockerfile, each FROM instruction will start a new phase. In v2021.1, you can now fold the stages and see a clear dividing line between them.
Cancel Docker operation
If you decide to stop a running Dockerfile, you can easily stop it in the " Sever" tool window. Select the running project, bring up the context menu, and click Stop Deploy .
Environment variables and macros mounted by Docker
When using bind mount, you can now enter the path of a directory on the host faster. The completion mechanism allows you to select macros and environment variables in the bind mount options in Run/Debug.
Image completion in Dockerfiles
Adding image names becomes easier, because code completion is now available for them. Take a look:
