Usage with docker

[flohw]

I want to use this tool inside a php docker container.
I get the error "Notice: Undefined index SHELL in bamarni/symfony-console-autocomplete/symfony-autocomplete on line 68"

Is it possible to run or update the scripts to be able to run inside a docker container ?

Thanks.

Strangely enough I've just seen the same issue.
docker exec -it php bash gives me a shell prompt inside my PHP-FPM container.
Running set | grep SHELL and I see SHELL=/bin/bash.
Running php -i | grep SHELL and I get nothing. My variables_order doesn't include E, so no environment variables added, but even php -d variables_order=EPGCS -i | grep SHELL yields no joy.

I think, if you want to run this, you'll need to provide the shell value manually using the --shell option (see https://github.com/bamarni/symfony-console-autocomplete/blob/master/src/DumpCommand.php#L23).

php -d variables_order=GPCSE -r 'print_r($_ENV); shows the environment variables that are being presented to PHP in the docker container. No SHELL. No OS.

Based upon moby/moby#33794, the only solution I can find at the moment is to supply the SHELL env to the docker exec command.

docker exec -e COLUMNS="tput cols" -e LINES="tput lines" -e SHELL=bash -it php bash

Running symfony-autocomplete in the container now generates the completion code without the error.

Updated README with notes regarding the lack of the SHELL environment variable when using docker exec to connect to a container.
