How to execute the partial execute for Terraform

There is an option -target for targetting the specific resources which you want to create with apply command or plan command. Sometimes, we faced the situation, new resources should be created first and update/destroy should be created later. In case of that, you can use the below commands.

New Resources Only

echo "terraform apply $(terraform plan -no-color | grep '\+ ' | grep -v 'new resource required' | grep -v 'create' | sed 's/\+ /\-target\=/g' | sed 's/$/ \\/g')"

Update Resources Only

echo "terraform apply $(terraform plan -no-color | grep '\~ ' | grep -v 'update in-place' | sed 's/\~ /\-target\=/g' | sed 's/\ //g' | sed 's/$/ \\/g')"
