I have this Dockerfile:
FROM ubuntu:17.04 # Must have packages RUN apt-get update && apt-get install -y nano zsh curl git # Instal Oh my Zsh RUN bash -c "$(curl -fsSL )" RUN sed -i -- 's/robbyrussell/sonicradish/g' /root/.zshrc # Add none root user RUN adduser admin USER admin I'm connecting with the admin user with the zsh shell.
docker exec -ti linux zsh I'm adding a non-root user (admin).
I still want to execute a sudo command with this user, but it errors out:
$ sudo apt-get install vim zsh: command not found: sudo Same message with bash shell.
How can I run sudo commands with a non-root user?
When I don't use sudo I get a permission error:
$ apt-get install vim E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied) E: Unable to lock the administration directory (/var/lib/dpkg/), are you root? 2 Answers
This is what I would do
FROM ubuntu:17.04 # Must have packages RUN apt-get update && apt-get install -y vim nano zsh curl git sudo # Install Oh my Zsh RUN bash -c "$(curl -fsSL )" RUN sed -i -- 's/robbyrussell/sonicradish/g' /root/.zshrc # Add none root user RUN useradd admin && echo "admin:admin" | chpasswd && adduser admin sudo USER admin Just create your non root user and add it to the sudoers group:
FROM ubuntu:17.04 RUN apt-get update RUN apt-get install sudo RUN adduser --disabled-password --gecos '' admin RUN adduser admin sudo RUN echo '%sudo ALL=(ALL) NOPASSWD:ALL' >> /etc/sudoers USER admin
