![]() That’s all from this post, please do post your queries and feedback in below comments section. Great, above confirms that we have successfully created a sudo user. Output of above two commands would look below: If output is ‘ root’ then it means user has sudo privileges and can run perform administrative tasks. 1 Answer Sorted by: 2 You need to change the default user in system, see configuration below. ![]() ![]() Now run any administrative command by writing sudo in infront of it. To test sudo user first switch to sudo user from your current user with help su command, Now run the same two commands that we use on Ubuntu Linux, # adduser sysops Once the sudo package is installed then sudo group and its entry in sudoers file will be populated automatically. So, to create a sudo user on Debian 10 / 11, first install sudo package using following apt command. The process can be completed using the usermod or gpasswd commands and testing the new user account with the sudo command. Output of above Command would look like below:įrom Debian 10 and Debian 11 onwards, sudo package is not the part of default OS installation because of that sudo group is not available by default. The user doesn't specifically need to exist in the container's /etc/passwd file.Above command will prompt to set the password and other details. If file permissions really matter, you can specify the numeric host user ID to use when you launch the container. Ideally that's the end of the story: your code is built into your image and it stores all of its data somewhere external like a database, so it doesn't care about the host user space at all (there by default shouldn't be docker run -v or Docker Compose volumes: options). When you describe the default way to run the container, only then switch to the non-root user. Next, use the ssh command to log in as root user: ssh rootyour-cloud-server-ip-here ssh Step 2 Create a new user account on Ubuntu. To add a user to the sudoer list, you must add it to the sudo group. Now you want this user to be able to run commands with sudo. This includes installing your application. Basics How to Give Sudo Access to a User in Ubuntu Abhishek Table of Contents So you added a new user to your Ubuntu system. Still in your Dockerfile, do almost everything as root. RUN adduser -system -group -no-create-home appuser You can also add them to groups (usermod), reset their passwords (passwd), or give them sudo privileges (visudo). To delete the user and their home directory, you want the 'deluser -remove-home maxn' command. It does not need a password, login shell, home directory, or any other details. To create a new user named 'maxn' in Ubuntu, use the command 'sudo adduser maxn'. In your Dockerfile, create some non-root user. The typical practice I'm used to works like this: The exception is when sharing files with the host using bind mounts, but there it's better to specify this detail when you start the container. user is not in the sudoers file error list of all user groups including sudo group sudoers configuration file root login user mod add user to sudo visudo. In order to add a user to sudoers, you have to use the usermod command and the capital G (for secondary groups). Since your containers have some isolation from the host system, you don't generally need containers to have the same user names or user IDs as the host system. RUN apt-get update & apt-get install -y some-package In the context of your question, if you've already switched to some non-root user, and you need to run some administrative command, use USER to switch back to root. ![]() sudo is also hard to script, and it's very hard to usefully maintain a user password in Docker (writing a root-equivalent password in a plain-text file that can be easily retrieved isn't a security best practice). In Docker you almost never need sudo, for three reasons: it's trivial to switch users in most contexts you don't typically get interactive shells in containers (how do I get a directory listing from inside the cron daemon?) and if you can run any docker command at all you can very easily root the whole host. (How do I add a user to my PostgreSQL server with sudo privileges? How do I add a user to my Web browser?) If you ask this question about other processes, it doesn't really make sense. Generally you should think of a Docker container as a wrapper around a single process.
