# Inject custom root certificate authorities if needed
# Docker does not have a good conditional copy statement and requires that a source file exists
# to complete the copy function without error. Therefore the README.md file will be copied to

# Additional Docker image root certificate authorities
If you require additional certificate authorities for your Docker image:
* Add ASCII PEM encoded .crt files to this directory
* The files will be copied into your docker image at build time.
To update manually copy the .crt files to /usr/local/share/ca-certificates/ and run sudo update-ca-certificates.
