By far the majority of these were variables which were not quoted. While, yes, right now we can guarentee most of these variables will never contain spaces, this could someday change and applying quoting as a universal rule prevents future mistakes. The ARGS="$@" -> "$*" change is purely stylistic and mainly is used to indicate the intent that we actually wanted to concatenate all the args by spaces, not keep them seperated as "$@" would in many situations, but not this one. Several warnings remain, in places where we intentionally want to split a variable on whitespace, or otherwise do what shellcheck is warning us against. Of note is shellcheck warning SC2166, which says to prefer [ foo ] || [ bar ] over [ foo -o bar ] as the -a and -o flags have differing behaviour on some systems. I've opted to keep these for now, since the version check test command would need to be replaced by a LOT of subshells to achieve the same effect, which feels dirtier.
Weave Scope - Monitoring, visualisation & management for Docker & Kubernetes
Weave Scope automatically generates a map of your application, enabling you to intuitively understand, monitor, and control your containerized, microservices based application.
Understand your Docker containers in real-time
Choose an overview of your container infrastructure, or focus on a specific microservice. Easily identify and correct issues to ensure the stability and performance of your containerized applications.
Contextual details and deep linking
View contextual metrics, tags and metadata for your containers. Effortlessly navigate between processes inside your container to hosts your containers run on, arranged in expandable, sortable tables. Easily to find the container using the most CPU or memory for a given host or service.
Interact with and manage containers
Interact with your containers directly: pause, restart and stop containers. Launch a command line. All without leaving the scope browser window.
Getting started
sudo curl -L git.io/scope -o /usr/local/bin/scope
sudo chmod a+x /usr/local/bin/scope
scope launch
This script will download and run a recent Scope image from the Docker Hub.
Now, open your web browser to http://localhost:4040. (If you're using
boot2docker, replace localhost with the output of boot2docker ip.)
For instructions on installing Scope on Kubernetes, DCOS or ECS, see the docs.
