An script that infers terraform resource move and generates 'terraform state mv ...' commands.
Put generate_state_mv.sh and infermv files into your $PATH directory.
curl https://raw.githubusercontent.com/bigwheel/tfinfermv/master/infermv -o ~/bin/infermv
curl https://raw.githubusercontent.com/bigwheel/tfinfermv/master/generate_state_mv.sh -o ~/bin/generate_state_mv.sh
chmod +x ~/bin/infermv ~/bin/generate_state_mv.sh- Go your Terraform root module
- Change your terraform configuration files
- Run
generate_state_mv.sh {{similarity_threshold - default 1.0}}
For more details, see this test case.
How many property values are needed for same resource determination.
If you change only one name of single resource, property values does not changed. Then you don't have to change Similarity Threshold from 1.0. However, if you change both resource property values and name, resource Similarity must go down under 1.0.
For example, a resource has 8 properties and 2 properties changed, Similarity is (8 - 2) / 8 = 0.75. Therefore no outputs for the resource when similarity_threshould is greater than 0.75.
You can specify any value as similarity_threshold, but I suggest use 0.7 ~ 1.0 value. If you need the value lower than 0.7, you should separate resource move commit and resource property change commit.
