GIS Tiling Cluster Creation

SuperMap iManager supports to ‘one-click’ creating GIS Tiling Cluster, please refer to the following steps:

1. Open Sites Management on the left navigation bar.
2. Clicks on + Create.

3. Fills in the name of the GIS Tiling Cluster environment, and select GIS Tiling Cluster in the Site type.

   Advanced Options:

   • iServer-master External Port: Set the port of iServer-master access address, a random port would be used if not set.
   • Use Service Mesh: Click to open service mesh function, the site is available to achieve service trace and service metrics. Modify the value of deploy_istio_enabled to ‘true’ in the ‘values.yaml’ file of iManager deployment package first if you want to use service mesh, please refer to Guides > Deployment Guide > Install iManager.

   • Resources Allocation: Set the limitation of CPU and Memory of the Site. The CPU/Memory in the Site is different to the CPU/Memory in hardware machine, the CPU/Memory in the Site is the CPU/Memory occupy of a service node in Kubernetes, the total CPU/Memory of the Site is equal to the sum of CPU/Memory of service nodes.

     • CPU(Required): Set the maximum available CPU of the Site.
     • Memory(Required): Set the maximum available Memory of the Site.
     • Pods: Set the maximum number of available pods in the Site.
     • Default container CPU limit: Set the maximum available CPU of a single container when creating.
     • Default container Memory limit: Set the maximum available Memory of a single container when creating.

   Notes:
   If the Site enable Service Mesh, each service node would create a istio-proxy, a istio-proxy occupies 2 core CPU and 1 GB Memory, the total CPU/Memory of the Site equal to the sum of CPU/Memory of service nodes plus the occupy of the istio-proxy.

4. Clicks on OK.
5. Check the status on the GIS Tiling Cluster page, while the status change to ‘Normal’, the GIS Tiling Cluster created successfully.
