linux - How to write the docker script such that sudo works in Docker user? -


i've ran empty docker container ubuntu , created sudo user such:

user@server$ docker run -it ubuntu bash  root@6da1c5bc7f93:/# apt-get update root@6da1c5bc7f93:/# apt-get -y install sudo  root@6da1c5bc7f93:/# useradd -m -p mosesdocker -s /bin/bash ubiwan root@6da1c5bc7f93:/# usermod -ag sudo ubiwan  # add user sudo list root@6da1c5bc7f93:/# su - ubiwan  # login ubiwan user

and when logged in ubiwan, password doesn't seem mosesdocker specified useradd -m -p mosesdocker -s /bin/bash ubiwan. i've typed correct password get:

to run command administrator (user "root"), use "sudo <command>". see "man sudo_root" details.  ubiwan@6da1c5bc7f93:~$ sudo su [sudo] password ubiwan:  sorry, try again. [sudo] password ubiwan:  sorry, try again. [sudo] password ubiwan:  sudo: 3 incorrect password attempts

why so?

is possible use sudo in docker? "suggested" perform sudo actions in docker?

how write docker script such sudo works in docker user?

you need set password user root using passwd.

first of type exit if logged in ubiwan. root type:

passwd ubiwan

give password user. can use sudo ubiwan user password
