terraform show returning 4 json objects-CodePudding

What specific syntax must be changed below in order for the terraform cli to return only one json object describing state instead of 4 json objects?

The command we are currently running is:

terraform show --json

The results we get from the above command include 4 json objects as follows:

What specifically do we have to change in order to receive one single json object in response which summarizes the state within that one single json object?

CodePudding user response：

This is not a standard terraform show --json output. I suspect that you set TF_LOG to DEBUG or INFO. Thus you have to change that env variable to normal value. For example, if you run it in bash on linux you can change it in one line as follows:

TF_LOG=ERROR terraform show --json

Alternatively, in an os-agnostic language like Python, you would use two different lines to first set TF_LOG=ERROR on one line using os.environ and then run a shell command on a second line to run terraform show --json using something like subprocess.popen. Remembering of course to re-set TF_LOG afterwards to whatever the user has as its default.
