Configuring your Deployment with Patterns, Filters and Applications
Meshery now comes with built in support for service mesh patterns, WASM filters and application workloads. Users can use Meshery to manage these artifacts and use them with their service mesh deployment.
Service Mesh Patterns
Users can use Meshery UI or mesheryctl to manage service mesh patterns.
Pattern Management Through Meshery UI
Meshery also comes with seed patterns when users start Meshery for the first time. These patterns cover common use cases and examples for you as you explore Meshery.
Users can also import these patterns to their remote provider from this sample repository.
Once these patterns are imported, you can then edit these patterns or use the pattern configurator to configure them according to your requirements.
Pattern Management Through Meshery CLI
You can also manage service mesh patterns through Meshery’s CLI, mesheryctl.
mesheryctl pattern subcommand lets you import and apply patterns to your cluster.
For example, if you have your pattern written in a file say,
istio-bookinfo.yaml which deploys Istio service mesh and onboards the BookInfo app on Istio, you can use mesheryctl to apply this pattern as shown below:
mesheryctl pattern apply -f istio-bookinfo.yaml
If you already have a pattern imported into Meshery, you can apply the pattern by name.
mesheryctl pattern apply BookInfoApp
This will apply the pattern BookInfoApp, which has already been imported into Meshery.
See mesheryctl Command Reference for more details on the
Meshery can be used for managing WebAssembly Filters through the UI or the CLI.
Filter Management Through Meshery UI
Like patterns, Meshery also comes with some sample WebAssembly Filters for you to experiment.
You can also import these filters manually to your provider from the wasm-filters repo.
Meshery’s sample application ImageHub will let you test out configuring these filters out-of-the-box.
You can onboard ImageHub to an installed service mesh as shown below.
Filter Management Through Meshery CLI
You can also manage WASM filters through Meshery’s CLI, mesheryctl.
mesheryctl filter subcommand lets you import and configure filters in your service meshes.
mesheryctl filter apply -f metrics_collector_bg.wasm
If you already have a filter imported into Meshery, you can configure the filter by name.
mesheryctl filter apply metrics_collector_bg
Meshery can also manage your Kubernetes applications and can onboard/offboard them of deployed service meshes.
Managing Applications Through Meshery UI
Meshery has a set of sample applications which you can use to quickly test out your deployment.
You can also bring in your own applications by uploading it from filesystem or importing it from a URL.
The application files can be described in Kubernetes manifest format or pattern format.
You can also run the same application on different service meshes and compare the performance. See Performance Management with Meshery for more details.
Managing Applications Through Meshery CLI
mesheryctl app subcommand lets you manage your custom application workloads with Meshery.
You can onboard/offboard applications from your mesh as shown in the example below.
mesheryctl app onboard imagehub.yaml
mesheryctl app offboard imagehub.yaml
