Amazon web services – Copy environment variables from one Elastic Beanstalk environment to another

Is there a bash command I can run to copy all the environment variables from one AWS Elastic Beanstalk environment to another? I’m trying to copy to a new environment, so assume that the target environment has no environment variables that need removing.

I’m aware of eb printenv and eb setenv, but these were not designed to work together.

    You can string them together with a bit of bash magic:

    eb setenv -e <TARGET_ENVIRONMENT> 
`eb printenv <SOURCE_ENVIRONMENT> | 
sed 's/ = /=/' | sed 's/ Environment Variables://'`

    If you prefer, you can create the following bash function:

    function eb-copy-env {
    # Usage: eb-copy-env <source_environment> <dest_environment>
    test "$1" && test "$2" || { echo "Usage: eb-copy-env <source_environment> <dest_environment>"; return 1; }
    SOURCE_VARS=$(eb printenv $1) || { echo $SOURCE_VARS; return 1; }
    SOURCE_VARS=$(echo $SOURCE_VARS | sed 's/Environment Variables://' | sed 's/ = /=/g')
    echo $SOURCE_VARS
    echo -e "nBeginning copy"
    eb setenv -e $2 $SOURCE_VARS
    echo -e "nCopy successful"
}

    Zag’s answer gave me the right idea, but didn’t quite work for me. Possibly because of a newer ebcli version. I have:

    $ eb --version
EB CLI 3.20.10 (Python 3.11.7 (main, Dec  8 2023, 14:22:46) [GCC 13.2.0])

    The following function works with the above version:

    function eb-copy-env {
  # Usage: eb-copy-env <source_environment> <dest_environment>
  test "$1" && test "$2" || { echo "Usage: eb-copy-env <source_environment> <dest_environment>"; return 1; }
  vars=$(eb printenv "$1") || { echo "$vars"; return 1; }
  vars=$(echo "$vars" | sed '/Environment Variables:/d;s/ = /=/;s/ = /=/;s/^ *//')
  echo "$vars"
  eb setenv "$vars" --environment "$2"
}
