红帽全球峰会第 19 章 Using Toolbx for development and troubleshooting
Installing software on a system presents certain risks: it can change a system’s behavior, and can leave unwanted files and directories behind after they are no longer needed. You can prevent these risks by installing your favorite development and debugging tools, editors, and software development kits (SDKs) into the Toolbx fully mutable container without affecting the base operating system. You can perform changes on the host system with commands such as less, lsof, rsync, ssh, sudo, and unzip.
The Toolbx utility performs the following actions:
-
Pulling the
registry.access.redhat.com/ubi10/toolbox:latestimage to your local system - Starting up a container from the image
- Running a shell inside the container from which you can access the host system
Toolbx can run a root container or a rootless container, depending on the rights of the user who creates the Toolbx container. Utilities that would require root rights on the host system also should be run in root containers.
The default container name is rhel-toolbox.
19.1. Starting a Toolbx container
You can create a Toolbx container by using the toolbox create command. You can then enter the container with the toolbox enter command.
Procedure
Create a Toolbx container:
As a rootless user:
$ toolbox create <mytoolbox> Created container: <mytoolbox> Enter with: toolbox enter <mytoolbox>As a root user:
$ sudo toolbox create <mytoolbox> Created container: <mytoolbox> Enter with: toolbox enter <mytoolbox>Verify that you pulled the correct image:
[user@toolbox ~]$ toolbox list IMAGE ID IMAGE NAME CREATED fe0ae375f149 registry.access.redhat.com/ubi10/toolbox:latest 5 weeks ago CONTAINER ID CONTAINER NAME CREATED STATUS IMAGE NAME 5245b924c2cb <mytoolbox> 7 minutes ago created registry.access.redhat.com/ubi10/toolbox:latest
Enter the Toolbx container:
[user@toolbox ~]$ toolbox enter <mytoolbox>
Verification
Enter a command inside the
<mytoolbox>container and display the name of the container and the image:⬢ [user@toolbox ~]$ cat /run/.containerenv engine="podman-4.8.2" name="<mytoolbox>" id="5245b924c2cb..." image="registry.access.redhat.com/ubi10/toolbox:latest" imageid="fe0ae375f14919cbc0596142e3aff22a70973a36e5a165c75a86ea7ec5d8d65c"
