近十年來（其實應該超過十年了），敏捷開發逐漸在軟體工程中佔有一席之地，這個的定義大概就是如果有人說他做軟工的，那你可能會回一句「所以你對 Agile 應該很熟吧」

Step 0: create snapshot from desired disk, example name: disk-snapshot-20171026

Consider the following scenario: you are going to rolling update your cluster, and it turns out your network bandwidth is limited for some reason and size of built docker image is not small enough. What’s worse, every instance of cluster will need to pull the docker image before start-up…

It happens the docker daemon wasn’t alive when I login to the console.

When reading salt’s source code, it seems we have a ‘source_hash_update’ option on “archive.extracted”, however when I added so, salt complains:

Warnings: 'source_hash_update', 'group' and 'user' are invalid keyword
              arguments for 'archive.extracted'. If you were trying to pass
              additional data to be used in a template context, please populate
              'context' with 'key: value' pairs. Your approach will work until
              Salt Carbon is out. Please update your state files.
