Kubernetes: dump all keys in secret to files:

secretdump.sh

# Requirements: kubectl and yq ( https://github.com/kislyuk/yq )
# This will take every key/value in a secret, base64 decode the value, and dump the result to
# a file named as the key name
SECRET=credentials-staging NAMESPACE=staging
for i in `kubectl -n ${NAMESPACE} get secret ${SECRET} -o yaml --export|yq -r '.data | keys[]'`
do
  echo "Dumping ${i}"
  kubectl -n ${NAMESPACE} get secret ${SECRET} -o yaml --export|yq -r '.data."'${i}'"' | base64 -d > ${i}
done
