ENTRYPOINT [ "nginx", "-g", "daemon off;" ]
#
# -g 'daemon off' :
# daemon off, to avoid the main process of nginx to quit after creating its childs, and therefore make docker exit

#
# ssl certificate :
# openssl faq : https://www.openssl.org/docs/faq.html
# openssl req : create ertificate request, and optionally create self signed certificates
# openssl req man : https://www.openssl.org/docs/man1.0.2/man1/openssl-req.html
# exemple of openssl with nginx on docker : https://www.johnmackenzie.co.uk/posts/using-self-signed-ssl-certificates-with-docker-and-nginx/
#
# usually the steps are :
# - create a server private key : `openssl genrsa -out server.key 2048`
# - create a CSR (certificate signing request) with the key : `openssl req -new -key server.key -out www.exemple.com.csr`
# - it will ask for :
# - Country Name (2 letter code)
# - State or Province Name (full name)
# - Locality Name (eg, city)
# - Organization Name (eg, company)
# - Organizational Unit Name (eg, section)
# - Common Name (eg, fully qualified host name)
# - Email Address (put nothing)
# - now ask to a CA (certificate authority) for a certificate.crt by giving them your request.csr
#
# alternatively we can generate our self-signed certificate with the `openssl req` command :
# - `x509` option is used to output a certificate instead of a certificate request
# - a request is created from scratch, if it is not given with `-in`
# - `newkey` generate a new private key, unless `-key` is given
# - `nodes` create a private key without encryption (no passphrase needed)
#
