# NOTE: The ampersand hell in this block is needed because docker-inspect uses go templates,
|
|
# which uses double ampersands as delimiters, just like Jinja does. If you want to understand
|
|
# the template, just replace all instances of {{ `{{` }} with {{ and {{ '}}' }} with }}.
|
|
# It will output something like the following:
|
|
# nginx:1.15,gcr.io/google-containers/kube-proxy:v1.14.1,gcr.io/google-containers/kube-proxy@sha256:44af2833c6cbd9a7fc2e9d2f5244a39dfd2e31ad91bf9d4b7d810678db738ee9,gcr.io/google-containers/kube-apiserver:v1.14.1,etc...
