terraform initcommand, you should get an error. Read the error and go to the line in themain.tffile where the error is. - Fix the cycle error you get due to the security groups expecting the other to be already created.
- Check the formatting of your code, and then initialize your working directory again. If the error is fixed, move on to the next step in your deployment.
- After running the
- Deploy Your Resources
Once you have worked past the error and successfully inilized your working directory, validated your code, and ran the plan, deploy your resources.
