Demoing cgr.dev tag history

We're going to use the new tag history API to see tag updates to cgr.dev/chainguard/static:latest!

First, exchange your Chainguard token for a registry token. This assumes you've set up auth with chainctl auth configure-docker:

tok=$(curl -H "Authorization: Bearer $(echo 'cgr.dev' | docker-credential-cgr get)" -v "https://cgr.dev/token?scope=repository:chainguard/static:pull" | jq -r .token)

container-report

This is an experimental tool that emits a JSON report of the contents of an image.

It's current intended use is to be passed two images and to have their reports diffed using diff.

Example:

imjasonh

function gauth() {
  gcloud auth login && gcloud auth application-default login
}

# Diff two image filesystems
function cdiff-fs() {
  diff \
    <(crane export $1 - --platform ${3:-linux/amd64} | tar -tvf - | sort) \
    <(crane export $2 - --platform ${3:-linux/amd64} | tar -tvf - | sort)
}

imjasonh

# Diff two image filesystems
function cdiff-fs() {
  diff \
    <(crane export $1 - --platform ${3:-linux/amd64} | tar -tvf - | sort) \
    <(crane export $2 - --platform ${3:-linux/amd64} | tar -tvf - | sort)
}
# Diff two image configs
function cdiff-cfg() {
  diff \
    <(crane config $1 --platform ${3:-linux/amd64} | jq) \
