podman-run:tldr:004cb
This command is using the podman run
command to run a container using Podman, which is a Linux container runtime tool. Let's break down the components of this command:
-
--env '${variable}=${value}'
sets an environment variable (variable
) with a specific value (value
) within the container. The single quotes ('
) around the variable allow it to be expanded to its value. -
--env ${variable}
sets an environment variable (variable
) with its existing value from the current shell environment. This is without any specific value assigned to it within the command. -
${image:tag}
refers to the specific container image you want to use, with the formatimage:tag
.image
represents the name of the container image, andtag
specifies a particular version or variant of that image. -
${command}
specifies a command that you want to execute within the container. This command will be passed to the container, and it will execute it when the container starts.
Overall, this command is instructing Podman to run a container using a specified image and tag, while also setting environment variables within the container. It will then execute a specific command within the container once it's started.
