NAME
|
|
$(basename $0) - Run a command in scylla's frozen toolchain docker build image.
|
|
|
|
SYNOPSIS
|
|
$0 [OPTIONS --] [command [arg ...]]
|
|
|
|
DESCRIPTION
|
|
$(basename $0) is used mainly to build scylla in a docker image containing
|
|
a frozen version of the toolchain.
|
|
|
|
When no command is provided, $(basename $0) runs an interactive shell in
|
|
the docker instance. The image to use is taken by default from "$(dirname $0)/image".
|
|
It may be overriden using the --image option.
|
|
|
|
When providing docker options, the options list must be terminated with \`--'.
|
|
|
|
