Dockerfile sudo command not found9/20/2023 ![]() The following sections will discuss them in detail. The first is to use the right package manager for your container, without changing the distribution, and the other option is to entirely change the distribution to something like Ubuntu, so it no longer bothers you. So basically, there are two main fixes for this. I am tinkering with a Docker container that I created using the following simple Dockerfile: FROM ubuntu CMD 'tail','-f','/dev/null' Inside the container, as the root user, I try running visudo and get the following response: bash: visudo: command not found. If you now try to use apt inside an alpine linux container (or inside a Dockerfile defined with alpine), you’d get the error message. In Alpine Linux, the package manager is called apk, while in Debian-based distributions like Ubuntu, the package manager is called apt. If you are installing Docker on a Linux-based operating system, ensure you configure Docker so it can be managed as a non-root user.

I am completely new to linux, tried to solve this issue by myself, but couldnt do it. If the file does not exist, create the file by running the following command: sudo vim. ![]() And if you happen to follow any online tutorials on using Docker for setting up your containers, it is very much possible that you had used the alpine linux image (without realizing it) and are now trying to use the package manager of some other distribution. I am trying to run docker commands from inside my container, but I always get the response 'bash: docker: command not found'. I have a linux server (completely new, web hosting, nothing is installed into it), and want to use a 'wget' command. If the file space in the Docker root directory is not adequate. Alpine Linux is the go-to distribution for use in docker containers. C’mon Sarker! What are you saying?Īs it appears to be, it is common to confuse the package manager of Debian-based distributions (such as Ubuntu), with the package manager of Alpine Linux. In fact, it is most probably the case for which you have faced the issue.
