lifecycle Blocks

Several different declaration types in the OpenTofu language support a nested block named lifecycle which includes settings that customize the plan and apply behavior of the associated object.

Each different type of declaration relates to objects that have a different lifecycle, and so the arguments available in these blocks are distinct for each parent block type:

• resource block lifecycle, for managed resources.
• data block lifecycle, for data resources.
• ephemeral block lifecycle, for ephemeral resources.
• module block lifecycle, for settings that relate to an overall module call instead of the individual resources inside it.

Although all of these features involve a block type named lifecycle, the expected arguments and associated behavior is defined separately for each context where a block of that type is allowed to appear.
