How Will the Multi-AZ Reconstruction of SWR Application Container Image Data Affect IEF?

Application Scope

CN South-Guangzhou, CN East-Shanghai1, and CN North-Beijing4

Application Scenario

When edge nodes access IEF through the air wall, proxy, gateway, or NAT, check whether IEF is affected by the multi-AZ reconstruction of SWR application container image data.

Checking Procedure

1. Run the following command to check the connection between the edge device and the domain name for accessing the application container image data. If the connection is normal, IEF is not affected by the multi-AZ reconstruction. Skip the subsequent steps.

   curl -i -k -v op-svc-swr-b051-10-38-19-62-3az.obs.cn-north-4.myhuaweicloud.com

   Connection output example:

   * Rebuilt URL to: op-svc-swr-b051-10-38-19-62-3az.obs.cn-north-4.myhuaweicloud.com/
   *   Trying 49.4.112.91...
   * Connected to op-svc-swr-b051-10-38-19-62-3az.obs.cn-north-4.myhuaweicloud.com (49.4.112.91) port 80 (#0)
   > GET / HTTP/1.1
   > Host: op-svc-swr-b051-10-38-19-62-3az.obs.cn-north-4.myhuaweicloud.com
   > User-Agent: curl/7.47.0
   > Accept: */*
   > 
   < HTTP/1.1 403 Forbidden
   HTTP/1.1 403 Forbidden
   < Server: OBS
   Server: OBS

2. Run the following command on a device that can access the Internet to obtain the IP address for accessing the application container image data:

   ping op-svc-swr-b051-10-38-19-62-3az.obs.cn-north-4.myhuaweicloud.com

   Output example:

   ping op-svc-swr-b051-10-38-19-62-3az.obs.cn-north-4.myhuaweicloud.com
   Pinging obs.lz02.cn-north-4.myhuaweicloud.com [49.4.112.91] with 32 bytes of data:
   ...

3. Modify the forwarding or mapping configuration of the domain name or IP address, including but not limited to the following scenarios:
   • For an air wall, add the mapping between IP:Port on the Internet and IP:Port on the intranet. If the /etc/hosts mode is previously used, add the mapping between the domain name for accessing the application container image data and the intranet mapping IP address to the /etc/hosts file.
   • For a proxy, add forwarding rules related to the domain name or IP address for accessing application container image data.
   • For a firewall, enable the restriction on the domain name or IP address for accessing the application container image data.

   Change the value based on your service environment.

4. Perform step 1 again to check whether the domain name for accessing the application container image data can be connected.
