# We create an NGINX Plus image based on the official NGINX Plus Dockerfiles (https://gist.github.com/nginx-gists/36e97fc87efb5cf0039978c8e41a34b5) and modify it by:
# 1. Explicitly installing the version of njs coded in the environment variable above.
# 2. Adding configuration files needed for proxying private S3 buckets.
# 3. Adding a directory for proxied objects to be stored.
# 4. Adding the entrypoint scripts found in the base NGINX OSS Docker image with a modified version that explicitly sets resolvers.

# Download your NGINX license certificate and key from the F5 customer portal (https://account.f5.com) and copy it to the build context
