Docker Apache2.4 HTTPS

Open port 443 on container, with a docker-compose file just add :

ports:
  - 443:443

Add virtualhost config :

Listen 443 https
 <VirtualHost *:443> 
     # Enable/Disable SSL for this virtual host.
     SSLEngine on
 
     SSLCertificateFile /etc/ssl/certs/cert.pem
     SSLCertificateKeyFile /etc/ssl/certs/cert.key
 </VirtualHost>

Create files with openssl and following config file named req.cnf : openssl req -x509 -nodes -days 99999 -newkey rsa:2048 -keyout cert.key -out cert.pem -config req.cnf -sha256

[req]
distinguished_name = req_distinguished_name
x509_extensions = v3_req
prompt = no
[req_distinguished_name]
C = FR
ST = IDF
L = Clichy
O = SensioGrey
OU = PoleTech
CN = sodebo.mydocker
[v3_req]
keyUsage = critical, digitalSignature, keyAgreement
extendedKeyUsage = serverAuth
subjectAltName = @alt_names
[alt_names]
DNS.1 = www.sodebo.mydocker
DNS.2 = fr.sodebo.mydocker
DNS.3 = en.sodebo.mydocker

This will generate a key.pem and cert.prem.

Copy them in proper folder during container build (to add in Dockerfile):

COPY ssl/cert.pem /etc/ssl/certs/cert.pem
COPY ssl/cert.key /etc/ssl/certs/cert.key
RUN echo '' > /etc/apache2/ports.conf

We delete default ports apache2 configuration, be sure to add Listen 80 in virtualhost config if you still use non https version.
