Toolbox makes it easy to use a containerized environment for everyday software development and debugging.On immutable operating systems, like Fedora Silverblue, it provides a familiar package-based environment in which tools and libraries can be installed and used.However, toolbox can also be used on package-based systems.
Toolbox takes the work out of using containers, by providing a small number of simple commands to create, enter, list and remove containers.It also integrates toolbox containers into your regular working environment, to make it easy for you to use them as an everyday development space.
In other words, toolbox containers look, feel and behave like a standard Linux command line environment.By connecting all this information, toolbox containers lose a certain amount of security gained by using the containers technology.Therefore, you should not treat toolbox containers as a sandbox where you can execute any script you would never run on any other system.
In most cases, when a command is run inside a container, the program from inside the container is used.However, there are a few special cases where the program on the host is used instead (using flatpak-spawn).One example of this is the toolbox command itself; this makes it possible to use toolbox from inside toolbox containers.
You might need to install additional packages or tools on Container-Optimized OSfor certain tasks, such as debugging. For example, debug node connectivity issues byinstalling tcpdump in toolbox.Although Container-Optimized OS does notinclude a package manager, you can use the pre-installedtoolbox utility to install any additional packages or tools you require. Using/usr/bin/toolbox is the preferred method for installing and running one-offdebugging tools.
You can customize the Docker image that toolbox uses, as well as the pathsavailable to toolbox in the root filesystem. These settings are located in thefile /etc/default/toolbox. The default /etc/default/toolbox file typicallyresembles the following:
To change the default settings, modify the /etc/default/toolbox file, orspecify new values for the variables in $HOME/.toolboxrc for the appropriateuser. For example, assuming that you want toolbox to use fedora:latest asits container, you can run the following commands:
You do not always have to enter toolbox to run commands in it. You can simplyprefix your commands with toolbox. For example, to install and run thestrace utility to trace the execution of the Docker daemon, you can do thefollowing:
The root filesystem of the host is accessible inside toolbox through the/media/root path. On the host, the root directory of toolbox is accessiblethrough the following path:/var/lib/toolbox/USER-gcr.io_cos-cloud_toolbox-VERSION/rootwhere USER is your user name and VERSION is the toolbox version number(for example, v20220722).
The toolbox installation consumes approximately 2-3 GB of diskspace in /var (disk usage varies with the Container-Optimized OS version). Tofree disk space used by toolbox, perform the following tasks depending on yourContainer-Optimized OS version:
I'm having a problem trying to move the design form window in visual studio, PictureThe designing window is on the top left, The reason is the space, another picture isAs you see, When I open the toolbox, It doesn't let me view the window anymore, while there is a huge unused space, It'd be really great if I can move the designing form to use all of the space I have on my monitor
