The prefixed spinner messages look odd because neither the download
confirmation prompts nor the hints on how to enter a container have
them. It's better to only prefix the debug and error messages so as to
disambiguate their origins.
Drop the Buildah dependency and the user-specific customized image
This works by configuring the toolbox container after it has been
created, instead of before. The toolbox script itself is mentioned as
the entry point of the container, which does 'exec sleep +Inf' once the
initialization is done.
A new command 'init-container' was added to perform the initialization.
It is primarily meant to be used as the entry point for all toolbox
containers, and must be run inside the container that's to be
initialized. It is not expected to be directly invoked by humans, and
cannot be used on the host.
As a result, the default name for the toolbox containers is now
fedora-toolbox-<version-id>, not fedora-toolbox-<user>-<version-id>.
For backwards compatibility, 'toolbox enter' and 'toolbox run' will
continue to work with containers using the old naming scheme.
A subsequent commit will create toolbox container names based on both
the base image and the user-specific customized image. This will make
it easier to read.
Check for /run/.toolboxenv later to accommodate entry point commands
A subsequent commit will add a new command to configure a toolbox
container after it has been created. This command is meant to be the
container's entry point, which runs before /run/.toolboxenv gets
created. Given that the entry point will be set by 'toolbox create'
it's safe to assume that it's a toolbox container anyway.
Check for flatpak-spawn(1) later - right before actually using it
A subsequent commit will add a new command to configure a toolbox
container after it has been created. This command is meant to run
inside the container without being forwarded to the host. Therefore,
just running inside a container doesn't mean that flatpak-spawn(1) is
mandatory.
This should help with toolbox containers created from images which
don't have flatpak-spawn(1) in them. eg., the fedora-toolbox base image
for Fedora 28.
Consolidate the code to forward commands to the host in one place
instead of doing it repeatedly for each command. This reduces the
levels of indentation in the code, making it easier to read.
A subsequent commit will add a new command to configure a toolbox
container after it has been created. This command is meant to be the
container's entry point, and will need to do things as root:root
relative to the user namespace.
Even though root:root is the default in 'podman create', explicitly
specifying it overrides any other value inherited from the
user-specific customized image. eg., older images had $USER as the
default user.
Add c.gh.debarshiray.toolbox to the container during 'podman create'
Commit 8127daa29ea08f35 added the com.github.debarshiray.toolbox label
to the user-specific customized image generated by the 'create'
command, which gets inherited by toolbox containers using the image.
However, there might be really old images lying around in users' caches
that don't have the label, and in those cases the damage can be
limited by adding it directly to the newly created toolbox container.
Moreover, a subsequent commit will remove the need for the
user-specific customized image, and which will make this change
mandatory.
