Log in to the ECS where kubectl has been installed. Create a description file named wordpress-deployment.yaml. wordpress-deployment.yaml is an example file name.
However, in a typical daily environment, the average data traffic of a single ECS is 100 KB/s, resulting in negligible CPU consumption.
If the shared disk is attached to multiple ECSs, these ECSs must belong to the same anti-affinity ECS group. If these ECSs fail to meet the anti-affinity requirement, the optimal performance of the shared disk cannot be achieved.
