Use the code from here https://github.com/docker-library/docs/tree/master/nginx#using-environment-variables-in-nginx-configuration

command: /bin/bash -c "envsubst < /etc/nginx/conf.d/mysite.template > /etc/nginx/conf.d/default.conf && exec nginx -g 'daemon off;'"

Got the error,

ERROR: for xxx_1 Cannot start service xxx: OCI runtime create failed: container_linux.go:344: starting container process caused "exec: "/bin/bash": stat /bin/bash: no such file or directory": unknown

ERROR: for xxx Cannot start service xxx: OCI runtime create failed: container_linux.go:344: starting container process caused "exec: "/bin/bash": stat /bin/bash: no such file or directory": unknown

Change /bin/bash to /bin/sh then works.

But why ?

You must've switched `image:` to the Alpine variant, which doesn't include Bash.

[qiulang]

But the image has bash!

Can you please share your full compose file so we can try to reproduce?

Sorry my mistake, it is indeed like you said, FROM nginx:stable-alpine as production-stage.
So no bash. My bad
