You dockerfile is a bit erratic, so I'll just provide a complete minimal example of building a ROS 1 package from source. ![]() RUN /bin/bash -c "bash /ros_entrypoint.sh" # HACK, replacing shell with bash for later docker build commands Older versions of Laravel (8.52.0 and below) do not support these variables and will not accept. The current dockerfile, which needs to be improved, looks currently like this: FROM ubuntu:16.04 Docker containers defined by the docker-compose.yml file. I have already tried the answers of other questions, dealing with the almost same issue: I am out of ideas, how I could achieve this. My goal is to achieve the same result with the building process of a dockerfile. However, when I run the resulting docker image ( sudo docker run -it ) and execute $ bash /ros_entrypoint.sh & cd ~/catkin_ws/ & catkin_make in the Ubuntu shell, the catkin_make is working as you can see in the following image: Unfortunately, the RUN catkin_make command inside inside of the dockerfile is not working in the building process, even executing the command RUN /bin/bash -c "bash /ros_entrypoint.sh" beforehand. Until now, my the building process of the dockerfile yields to the installation of Ubuntu 16.04 as well as ROS kinetic. Your comments and feedback are welcome.I am creating a dockerfile for creating automatically an Ubuntu 16.04 operation system on which ROS kinetic is installed. In this guide, we have demonstrated how to resolve the “ sudo command not found” error in Linux. Once youve installed the PostgreSQL server with apt-get install postgresql-9.1, its already set up and running so your steps 2 and 3 (run postgres and run initdb) are not necessary and in fact would conflict with what has already been set up.By running manually initdb youll end up with two postgres clusters. That means, you dont need sudo for anything. (substitude postgres with the real container name you get from docker-compose ps ) Now you are in the container as root. ![]() To confirm that the user has been added to the group, run: # groups tecmintįrom here, you can comfortably run commands using sudo without an issue at all. To do a backup of the postgres database in the container, you first have to enter the container (similar to how you do it): docker exec -it postgres bash. For example, to add user tecmint to the sudo group, run the command. # pacman -Sy sudoįrom here, you can add users to the sudo group. # yum install sudoįor Arch Linux, run the command. Then rebuild your image with docker build. Then install sudo using the yum command as shown. Starting from debian image you need to install sudo, you can do it by adding RUN apt-get update & apt-get install sudo -y to the beginning of your Dockerfile.

Or, run the docker image, and then connect to that image and run. ![]() ![]() FROM ubuntu RUN apt update RUN apt install vim or any package you want. First using Dockerfile and then docker build. The sudo package ships by default in most Linux distributions, and you should not have a problem using it. If its not working, check firewall of you laptop. This mitigates the risk of breaking the system in case a potentially dangerous command is executed. Usually, using sudo is the recommended way to run a Linux system instead of using the root user. Sudo, an abbreviation for superuser do, is a program that allows users to run commands or programs with root or elevated privileges.
