Remove the package from the packages line, as shown:. Save the change and the marketplace-operator will reconcile the CatalogSourceConfig. This guide walks developers through an example of creating applications from an installed Operator using the OpenShift Container Platform 4.
The Operators that have been installed to the cluster by the cluster administrator and are available for use are shown here as a list of ClusterServiceVersions CSVs. CSVs are used to launch and manage the software provided by the Operator. On the Installed Operators page, click Copied , and then click the etcd Operator to view more details and available actions:.

These objects work similar to the built-in native Kubernetes ones, such as Deployments or ReplicaSets , but contain logic specific to managing etcd. Click the Resources tab to see that your project now contains a number of resources created and configured automatically by the Operator. Verify that a Kubernetes service has been created that allows you to access the database from other Pods in your project. All users with the edit role in a given project can create, manage, and delete application instances an etcd cluster, in this example managed by Operators that have already been created in the project, in a self-service manner, just like a cloud service.
If you want to enable additional users with this ability, project administrators can add the role using the following command:. You now have an etcd cluster that will react to failures and rebalance data as Pods become unhealthy or are migrated between nodes in the cluster.
Most importantly, cluster administrators or developers with proper access can now easily use the database with their applications. For example, the built-in Pods resource contains a collection of Pod objects.
Custom Resource CR objects are created from CRDs that have been added to the cluster by a cluster administrator, allowing all cluster users to add the new resource type into projects. The Kind comes from the spec. To get information on a specific Kind of a CR, run:. Resource names are not case-sensitive, and you can use either the singular or plural forms defined in the CRD, as well as any short name.
The set of objects created by new-app depends on the artifacts passed as input: source repositories, images, or templates. With the new-app command you can create applications from source code in a local or remote Git repository. The new-app command creates a build configuration, which itself creates a new application image from your source code. The new-app command typically also creates a deployment configuration to deploy the new image, and a service to provide load-balanced access to the deployment running your image. OpenShift Container Platform automatically detects whether the Pipeline or Source build strategy should be used, and in the case of Source builds, detects an appropriate language builder image.
If you use a local Git repository, the repository must have a remote named origin that points to a URL that is accessible by the OpenShift Container Platform cluster. If there is no recognized remote, running the new-app command will create a binary build. If you use a private remote Git repository, you can use the --source-secret flag to specify an existing source clone secret that will get injected into your BuildConfig to access the repository.
You can use a subdirectory of your source code repository by specifying a --context-dir flag. To create an application from a remote Git repository and a context subdirectory:. If a Jenkinsfile exists in the root or specified context directory of the source repository when creating a new application, OpenShift Container Platform generates a Pipeline build strategy.
Override the build strategy by setting the --strategy flag to either pipeline or source. The oc command requires that files containing build sources are available in a remote Git repository. For all source builds, you must use git remote -v. If you use the Source build strategy, new-app attempts to determine the language builder to use by the presence of certain files in the root or specified context directory of the repository:.

After a language is detected, new-app searches the OpenShift Container Platform server for imagestreamtags that have a supports annotation matching the detected language, or an imagestream that matches the name of the detected language. If a match is not found, new-app searches the Docker Hub registry for an image that matches the detected language based on name.
Note that if this is done, build strategy detection and language detection are not carried out. Language detection requires the Git client to be locally installed so that your repository can be cloned and inspected.
You can deploy an application from an existing image. Images can come from imagestreams in the OpenShift Container Platform server, images in a specific registry, or images in the local Docker server. The new-app command attempts to determine the type of image specified in the arguments passed to it.http://lambertcastle.com/97-comprar-azitromicina.php

However, you can explicitly tell new-app whether the image is a container image using the --docker-image argument or an imagestream using the -i --image argument. If you specify an image from your local Docker repository, you must ensure that the same image is available to the OpenShift Container Platform cluster nodes. Create an application using an image in a private registry, specify the full container image specification:. You can create an application from a previously stored template or from a template file, by specifying the name of the template as an argument.
For example, you can store a sample application template and use it to create an application. To directly use a template in your local file system, without first storing it in OpenShift Container Platform, use the -f --file argument. When creating an application based on a template, use the -p --param argument to set parameter values that are defined by the template:. You can store your parameters in a file, then use that file with --param-file when instantiating a template. The new-app command generates OpenShift Container Platform objects that build, deploy, and run the application that is created.
Normally, these objects are created in the current project and assigned names that are derived from the input source repositories or the input images. However, with new-app you can modify this behavior.
An Introduction to R
A BuildConfig is created for each source repository that is specified in the command line. The BuildConfig specifies the strategy to use, the source location, and the build output location. For BuildConfig , two ImageStreams are usually created. One represents the input image. With Source builds, this is the builder image.

The second one represents the output image. If a container image was specified as input to new-app , then an imagestream is created for that image as well. A DeploymentConfig is created either to deploy the output of a build, or a specified image. The new-app command creates emptyDir volumes for all Docker volumes that are specified in containers included in the resulting DeploymentConfig.
The new-app command attempts to detect exposed ports in input images. It uses the lowest numeric exposed port to generate a service that exposes that port. In order to expose a different port, after new-app has completed, simply use the oc expose command to generate additional services. Other objects can be generated when instantiating templates, according to the template. When generating applications from a template, source, or an image, you can use the -e --env argument to pass environment variables to the application container at run time:.

The variables can also be read from file using the --env-file argument:. Any BuildConfig objects created as part of new-app processing are not updated with environment variables passed with the -e --env or --env-file argument. When generating applications from a template, source, or an image, you can use the --build-env argument to pass environment variables to the build container at run time:.
The variables can also be read from a file using the --build-env-file argument:.
When generating applications from source, images, or templates, you can use the -l --label argument to add labels to the created objects. Labels make it easy to collectively select, configure, and delete objects associated with the application. To see a dry-run of running the new-app command, you can use the -o --output argument with a yaml or json value.
