witmicko / mobile-cli Goto Github PK

The mobile cli focuses on a small set of commands to empower mobile focused developers to consume and take full advantage of the RedHat mobile suite of services ontop of Kubernetes / OpenShift.

It uses a language familiar to mobile developers and abstracts away some of the complexity of dealing with Kubernetes / OpenShift which can be initially daunting and overwhelming.

mobile get services

mobile provision fh-sync

mobile --namespace=myproject get sdkconfig

mobile create binding fh-sync keycloak

mobile create clientbuild <MobileClientID> <Git_Source_Url> [buildName]

mobile get buildartifact <clientBuildID> 

• have a local kubernetes or oc cluster via something like minikube or oc cluster up

oc login -u system:admin
oc create -f artifacts/mobileclient_crd.yaml

In OpenShift, add the following to the edit and admin roles

- apiGroups:
  - mobile.k8s.io
  attributeRestrictions: null
  resources:
  - mobileclients
  verbs:
  - create
  - delete
  - get
  - list
  - patch
  - update
  - watch

You can do this via the edit command in oc

oc edit clusterrole admin # add the above and save
oc edit clusterrole edit # add the above and save

• have the kubectl command line tool or the oc command line tool already installed
• It should be version k8s version 1.8 or OpenShift 3.7 or later
• create a new dir mkdir -p ~/.kube/plugins/mobile
• copy the plugin.yaml to the dir cp ./artifacts/cli_plugin.yaml ~/.kube/plugins/mobile
• install the mobile cli binary onto your $PATH

To access the plugin you can use the following command: kubectl plugin mobile <command>

You can also use it standalone as it will pick up on your kube configuration:

mobile --namespace=mine <command> notice we pass the namespace here.

Passing flags

To pass flags when using the plugin ensure to use the -- option

kubectl plugin mobile -- create client --<someflag>

The design of the cli API attempts to give a familiar feel to users familiar wil the kubectl and oc CLIs. It is also intended to use parlance familiar to mobile developers in order to help them become more productive and avoid needing to know the innards of various kubernetes resources.

In a similar fashion to the oc and kubectl CLI, we have some core resources that we work with. Some of these are backed by things like secrets while others are defined as custom resources.

• MobileClient: the mobile client is a resource that represents your mobile client app as part of the OpenShift UI. It gives us the context and information needed to show you relevant information around your particular mobile runtime as well as allowing us setup the different kind of client builds required.

• ClientConfig the client config, is a resource created by aggregating together all of the available service configs. This resource is configuration required in order to consume your mobile aware services from your mobile client. It is used by the client SDKs for the various mobile services.

• ServiceConfig: the Service Config stores information about a mobile aware service and is backed by a secret. This information is then used to populate your mobile client's config. This information could be anything but often is made up of values such as the URI of the service and perhaps some headers and configuration particular to that service.

• ClientBuild the ClientBuild is backed by a regular BuildConfig however the cli will help you create this BuildConfig with as little effort as possible. Allowing you to focus on just the mobile parts rather than needing to understand how to setup and manage a buildconfig and builds. For example, it will help you manage build credentials, and keys and ensure the build integrates seamlessly with the areogear mobile build farm .

• Binding the Binding is backed by a binding resource in the service catalog. Once again we try to remove the need to understand how to create the native objects so that you can focus on being productive and building your mobile app. When doing a binding, you will be able to integrate different mobile services together. For example when using sync and keycloak you can bind them together and have your sync service protected by keycloak. This is as simple as mobile bind fh-sync keycloak

get

- clients
    - get clients #returns a list of mobile clients within the current namespace
    - get client <clientName> # returns a single mobile client
- serviceconfig
    - get serviceconfigs # returns a list of mobile aware service configurations (this is the full unfiltered configuration data)
    - get serviceconfig <serviceName> #returns a single mobile aware service configuration (this is the full unfiltered configuration data) 
- clientconfig
    - get clientconfig # returns the filtered configuration as should be consumed by mobile clients making use of the sdks 
- clientbuild
    - get clientbuilds #returns a list of mobile client builds
    - get clientbuild <clientBuildName> #returns a single mobile client build
- integrations   
    - get integrations # returns a list of integrations between mobile aware services and their consumers
    - get integration <name> # return a single integration and the name of the services consuming it

create

- client
    - create client <clientName> <clientType> # will create a representation of the mobile client application
- serviceconfig
    - create serviceconfig # this command will likely prompt for needed imputs    
- integration
    - create integration <consuming_service_inst_id> <providing_service_inst_id> # will create the binding and pod preset and optionally redeploy the consuming service
    for example: mobile create integration fh-sync keycloak 
- clientbuild
    - create clientbuild <clientID> <git_Source> [buildName] # will create a Jenkins PipeLine based buildconfig likely will need a several option flags to cover
    things like credentials and keys

delete

- client
    - delete client <clientID> # removes the configmap or mobileclient object if we go with CRD
- serviceconfig
    - delete serviceconfig <configName> # remove the configur        
- integration
    - delete integration <consuming_service_inst_id> <providing_service_inst_id> # removes all the objects created when the integratio was enabled. 
    for example mobile delete binding fh-sync keycloak
- clientbuild
    - delete the buildconfig and any other related object that back the client build.
    example: delete clientbuild <clientBuildName>    

replace

start

- clientbuild <buildName>

stop

- clientbuild <buildName>
