Kubectl output options

Let's look at some basic kubectl output options.

Our intention is to list nodes (with their AWS InstanceId) and Pods (sorted by node).

We can start with:

kubectl get no

caps = Selenium::WebDriver::Remote::Capabilities.chrome(chromeOptions: { binary: "/Applications/Google\ Chrome\ Canary.app/Contents/MacOS/Google\ Chrome\ Canary", 
                                                                         args: [ "--headless" ]})

Before do
  @browser = Selenium::WebDriver.for :chrome, desired_capabilities: caps

# Example YAML configuration for the sidecar pattern.

# It defines a main application container which writes
# the current date to a log file every five seconds.

# The sidecar container is nginx serving that log file.
# (In practice, your sidecar is likely to be a log collection
# container that uploads to external storage.)

If your master.key has been compromised, you might want to regenerate it.

No key regeneration feature at the moment. We have to do it manually.

1. Copy content of original credentials rails credentials:show somewhere temporarily.
2. Remove config/master.key and config/credentials.yml.enc
3. Run EDITOR=vim rails credentials:edit in the terminal: This command will create a new master.key and credentials.yml.enc if they do not exist.
4. Paste the original credentials you copied (step 1) in the new credentials file (and save + quit vim)
5. Add and Commit the file config/credentials.yml.enc
