Additionally, the operator can set any environment variable in the container by using one or more -e flags, even overriding those mentioned above, or already defined by the developer with a Dockerfile ENV. If the operator names an environment variable without specifying a value, then the current value of the named variable is propagated into the container’s environment:
$ export today=Wednesday
$ docker run -e "deep=purple" -e today --rm alpine env
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
HOSTNAME=d2219b854598
deep=purple
today=Wednesday
HOME=/root
私は私のコンテナにドッキングウィンドウの実行-eを実行しようとした:
docker run -d -it myimage123 -e "myvar=blah"
私はこのエラーを取得する:
[FATAL tini (7)] exec -e failed: No such file or directory
