💡 Hint

Common Mistakes

Using a command that requires AWS CLI without setup

Not putting the command in quotes

The local-exec provisioner runs the command locally. Here, echo Hello World prints a message after resource creation.

💡 Hint

Common Mistakes

Using only the script name without shell command

Using terraform commands instead of shell commands

The local-exec provisioner runs the command locally. To run a script, use bash deploy.sh to execute the shell script.

💡 Hint

Common Mistakes

Not quoting the command string

Using commands that do not output directory

The command must be a string. Without quotes, Terraform will error. So "pwd" is correct.

4fill in blank

hard

Fill both blanks to run a local command that lists files in the current directory.

Terraform

resource "null_resource" "list_files" {
  provisioner "local-exec" {
    command = [1] [2]
  }
}

Drag options to blanks, or click blank then click option'

A"ls"

B"-l"

C"-a"

D"pwd"

💡 Hint

Common Mistakes

Using pwd instead of ls

Using options that do not list files

The command ls -l lists files with details. Both parts must be strings.

5fill in blank

hard

Fill all three blanks to run a local command that creates a directory named 'testdir' and lists its contents.

Terraform

resource "null_resource" "create_and_list" {
  provisioner "local-exec" {
    command = [1] && [2] [3]
  }
}

Drag options to blanks, or click blank then click option'

A"mkdir testdir"

B"ls"

C"-l"

D"rm -rf testdir"

Attempts:

3 left

💡 Hint

Common Mistakes

Using remove command instead of mkdir

Not combining commands properly

The command creates a directory mkdir testdir, then lists files with details ls -l. The && runs the second command only if the first succeeds.
