HAProxy Community Docs v2.2
Use the docker-compose.yml file with docker-compose to deploy the container. The image requires a configuration file named haproxy.cfg with your cluster settings and a ssl pem certificate called haproxy.pem.
# Generate the certificate
openssl pkcs12 -in cnpem.br.pfx -out cert.pem -nokeys -clcerts
# Generate the private key
openssl pkcs12 -in cnpem.br.pfx -out key.pem -nocerts -nodes
# Append key and crt
cat cert.pem > haproxy.pem
cat key.pem >> haproxy.pem
