Image Tag Format

Description

You can attach a custom tag to a private image to facilitate private image management.

A maximum of 20 tags can be added to an image. You can check on the console how many tags you can add.

Format

• For tag, the format is key.value. If a key is added, a tag is added. In other cases, the tag is updated.
  

  If a tag contains multiple decimal points, the content before the first decimal point is the key, and that after the first decimal point is the value. If a tag contains no decimal point, the value is regarded as an empty string.

• For image_tags, the format is {"key":"keyA", "value":"valueA"}. If a key already exists when you add it, the tag will be updated.
• A key contains 1 to 128 characters and cannot be left blank.
• A value contains 0 to 255 characters and can be an empty string.
• Keys must be unique for each tag.
• Keys can be:
  • Unicode characters (\u4E00 to \u9FFF)
  • Letters
  • Digits
  • Spaces and underscores (_) :+-@
    

    A key cannot start or end with a space.

• Values can be:
  • Unicode characters (\u4E00 to \u9FFF)
  • Letters
  • Digits
  • Spaces and underscores (_) :/+-@
    

    A value cannot start or end with a space.
