You can use the Docker run command if you don’t have a container or the Docker exec command if you already have a container running.
#HOW TO EDIT TEXT FILE IN TERMINAL UBUNTU HOW TO#
To conclude, in this article, we discussed how to create and edit a file inside a Docker container if you have access to the container’s shell. $ docker run -it -name=mycont bashĭoing so, you will get access to the container’s bash with vim editor already installed. Once you have executed the Docker build command on this Dockerfile to build the image, you can run a container using the Docker run command. The COPY instruction will copy all the files inside the container’s default working directory from the current directory in your host machine. FROM ubuntu:latestīy default, when you pull an Ubuntu image, you won’t find any text editor.

Repeat the above steps to create and edit files.Īnother way to do so and probably a better one, is to directly install the vim editor using the Dockerfile. If you already have a container running in the background, you can even use the Docker exec command to get access to the bash of the container. In this way, you can use any editor of your choice to edit files inside the container. To verify, use the cat command to print the contents inside the file. To save the content, press escape key to exit from insert mode, type :q, and press enter to save and quit. To insert content inside the file, you need to invoke the insert mode.
Now, you can install the vim package using the following command.
#HOW TO EDIT TEXT FILE IN TERMINAL UBUNTU UPDATE#
Before doing this, make sure you update the container # apt-get -y update You can use nano or install the vim package inside the container. If you want to edit a file inside the container, you will need access to a file editor. To verify the creation of the file, you can list all the contents. You can execute this command inside the container’s bash. To create a file, we can use the touch command Once you have access to the container’s bash, you can interact with it in the same way you would interact with your Linux/Ubuntu terminal. You will find that the mycont container that you created is actively running. Keeping this container bash running in the terminal, open a new terminal and execute the following command. You can even verify that the container is actively running by listing all the active containers.
Thus, when we run the above command, we will have access to the bash of the ubuntu container. Next, we have used the /bin/bash command which sets a default command to be executed as soon as the container is started. These options allow us to interact with the container by providing inputs. In the above Docker run command, we have used the -i and -t options which stands for interactive and pseudo-TTY. $ docker run -it -name=mycont ubuntu /bin/bash Let’s create and run an Ubuntu container. Either you can directly use a COPY instruction in a Dockerfile or create a file directly inside the container. To begin with, you need to first create an image such that when you create a container associated to that image, you have access to a text file inside the container. In this article, we will discuss exactly how to do so. But what if you want to edit the file inside the container? In simpler words, there might be situations when you have accessed the shell or the bash of the container and you want to edit files inside the container.
Moreover, you can use the COPY instruction inside a Dockerfile or even the Docker cp command to copy files inside the container from the local machine. Once you have specified the location of the build context using the Docker build command, you can build the image.

This includes the source code of your application, Dockerfile, other system files, etc. The Image build context contains all the files that you want to be included inside the container that you will be from that image. While creating Docker images, you specify the build context for the image.
