Using External Service to Store Binaries Resources¶

This document describes how to use third-party storage services to store Binaries resources and specify them during the installation process. There are two types of supported services: S3 compatible services (such as Minio) and non-S3 compatible services (such as Nginx).

Steps¶

Using S3 Compatible Service¶

For S3 compatible services, simply configure the clusterConfig.yaml, no further operations are required.

1. Configure the clusterConfig.yaml file by setting the parameters related to binaries as follows:

   apiVersion: provision.daocloud.io/v1alpha3
   kind: ClusterConfig
   metadata:
   spec:
     ..........
     binaries:
       type: external
       externalRepoEndpoint: https://external-repo.daocloud.io
       externalRepoUsername: rootuser
       externalRepoPassword: rootpass123
     ..........
   

   Note

   The given username should have read and write permissions for the bucket.

Using Non-S3 Compatible Service¶

For non-S3 compatible services, you need to manually import the offline binaries package offline/kubespray-binary/offline-files.tar.gz from the downloaded image offline package directory, and then configure the relevant parameters in the clusterConfig.yaml.

The following instructions assume that CentOS 7.9 x86_64 is used as the cluster node and Nginx is used as the HTTP server. In theory, other generic HTTP servers can also be supported, but pay attention to the mapping relationship between URL access paths and file paths.

1. Ensure that an available Nginx service exists, and the node where the service resides has login and file writing permissions.

2. Copy the binaries offline package from the bootstrap node to the node where the nginx service is located.

   Note

   The path of the binaries offline package is ./offline/kubespray-binary/offline-files.tar.gz

3. Determine the path that needs to be imported;

   1. Check the mapping relationship between the file path and the URL path on the Nginx service node through nginx.conf. The following example can be used as a reference:

      http {
          server {
              listen       8080;
              server_name  _;
              location / {
                  root   /usr/share/nginx/html;
                  index  index.html index.htm;
              }
          }
      }
      

      The above configuration indicates that the access root path of the nginx HTTP service is mapped to the local directory /usr/share/nginx/html.

   2. If Nginx is deployed in the conventional way, select the import path as /usr/share/nginx/html.

   3. If Nginx is deployed in a container, you need to mount the host path to the container, and the mounted host path corresponds to the mapped local path of the HTTP service in the container. That is, there is such a relationship: http-path -> container-path -> host-path. Therefore, the import path should be the host-path. The host-path needs to be confirmed manually according to the appendix.

4. Run the following command to import the offline binaries package:

   cat > import.sh << "EOF"
   [ ! -d "${MAPPING_PATH}" ] && echo "mapping path ${MAPPING_PATH} not found" && exit 1
   [ ! -f "${BINARIES_PKG_PATH}" ] && echo "binaries package path ${BINARIES_PKG_PATH} not found" && exit 1
   tar -xzvf ${BINARIES_PKG_PATH} --strip-components=1 -C ${MAPPING_PATH}
   EOF
   export MAPPING_PATH="/usr/share/nginx/html"
   export BINARIES_PKG_PATH="./offline-files.tar.gz"
   bash ./import.sh
   

   In the above command, the environment variable MAPPING_PATH represents the import path mentioned in step 3.

5. In the clusterConfig.yaml, configure the parameters related to binaries.

   apiVersion: provision.daocloud.io/v1alpha3
   kind: ClusterConfig
   metadata:
   spec:
     ..........
     binaries:
       type: external
       externalRepoEndpoint: http://10.0.1.1:8080
     ..........
   

6. After completing the above configurations, you can continue with the deployment of DCE 5.0 Enterprise.
