Squid proxy setup built from source within the Dockerfile, enabling build options needed for ssl bumping. The Dockerfile leaves the squid configuration as default, however, the docker-compose file mounts the configuration needed for ssl bumping.
The Squid configuration is based on the default configuration and follows the steps outlined in SslBumpExplicit and SslPeekAndSplice to setup ssl bumping.
Certificates are created automatically on startup, myCA.pem and myCA.der are used as shown in SslBumpExplicit documentation. myCA.der should be imported as described in the documentation.
