download wait-for-it.sh error

[vneyman]

Hi,

Below line in workbench Dockerfile is giving me an error. Cannot download it. What does this do and is it necessary?

RUN curl -fsSL -o /usr/local/bin/wait-for-it.sh https://raw.githubusercontent.com/rstudio/wait-for-it/master/wait-for-it.sh &&
# chmod +x /usr/local/bin/wait-for-it.sh

Thanks.

Hi @vneyman,
Does the environment you are running in have any networking restrictions or proxies that could be blocking these HTTPS requests?

This script is used to ensure that services are accepting TCP connections. For workbench, this is used in the startup entrypoint script to confirm the availability of the local job launcher service:

rstudio-docker-products/workbench/startup.sh

Lines 83 to 87 in 4c0eea1

	# Start Launcher
	if [ "$RSW_LAUNCHER" == "true" ]; then
	echo "Waiting for launcher to startup... to disable set RSW_LAUNCHER=false"
	wait-for-it.sh localhost:5559 -t $RSW_LAUNCHER_TIMEOUT
	fi

Please see rstudio/wait-for-it for a more detailed description of the wait-for-it.sh script.

Hope this helps!

Thank you. You're absolutely correct I do have a HTTPS restrictions. I will just copy the sh file into the appropriate directory using the Dockerfile.
