Replace /Applications/Docker/Docker Quickstart Terminal.app/Contents/Resources/Scripts/iterm.scpt with this.

iterm.scpt

set itermRunning to (application "iTerm" is running)
set scriptPath to quoted form of POSIX path of ((path to me as text) & "::" & "start.sh")
set user_shell to do shell script "dscl /Search -read /Users/$USER UserShell | awk '{print $2}'"

tell application "iTerm"
    activate
    if not (exists window 1) or (itermRunning = false) then
        reopen
    end if

    try
        tell current window
            set newTab to (create tab with default profile)
            tell current session of newTab
                write text "bash --login " & scriptPath
            end tell
        end tell
    on error
        tell current session of (create window with default profile)
            write text "bash --login " & scriptPath
        end tell
    end try
end tell

Thank you, it works perfect!!!

Thanks!!!

If you have multiple computers, easiest thing to do is to save this file to your iCloud drive and then link from it.

$ sudo mv /Applications/Docker/Docker\ Quickstart\ Terminal.app/Contents/Resources/Scripts/iterm.scpt /Applications/Docker/Docker\ Quickstart\ Terminal.app/Contents/Resources/Scripts/iterm.scpt.bak
$ sudo ln ~/Library/Mobile\ Documents/com~apple~ScriptEditor2/Documents/iterm.scpt /Applications/Docker/Docker\ Quickstart\ Terminal.app/Contents/Resources/Scripts/iterm.scpt

Thanks!!! It works very well!!!

Am I the only one getting this error?

With respect to "Expected end of line", I needed to replace in the .scpt file, "iTerm" with "iTerm2".

Yes master! This is it looking for I was.

This works. Thanks.

Cheers, thanks for sharing.
