Workflows

For more examples, see ./examples/ directory

# create a server with a nbd1 volume of 50G and rescue bootscript
$ SERVER=$(scw create trusty --bootscript=rescue --volume=50000000000 --wait)
# print the ip address of the server
$ echo "Your server is ready and is available at: $(scw inspect ${SERVER} -f .server.public_ip.address)"

Debug

scaleway-cli uses the debug package.

To enable debug you can use the environment variable DEBUG= as :

• DEBUG='*' scw ... to see debug for scaleway-cli and all dependencies
• DEBUG='scaleway-cli:*' scw ... to see debug for scaleway-cli
• DEBUG='node-scaleway:*' scw ... to see debug for node-scaleway

$ DEBUG='*' scw images
