Configure the Application

Updated at: Aug 05, 2019 GMT+08:00

Prerequisite

A server with at least 2 GB memory is ready for deploying the demo application.

  • You can use your own server (with Docker installed) or a HUAWEI CLOUD ECS to deploy the demo application. This application cannot be deployed in the HUAWEI CLOUD CCE clusters. For details about how to purchase a HUAWEI CLOUD ECS, see ECS documents.
  • You are advised to use the CentOS or Ubuntu for the ECS.
  • The Docker must be installed on the ECS. Take an ECS with CentOS as an example. Log in to the ECS, and run the following commands to install and start the Docker. If another OS is used, run its right command to install the Docker. For example, run the apt-get install docker command in Ubuntu.
    yum install docker
    service docker start
  • Unzip must be installed using the following command on the ECS. Otherwise, the demo application will fail to be installed.
    yum install unzip
