I am a devops engineer and application architect who spends their entire day developing automated docker deployments for custom applications from scratch and I manage all our reverse proxies and TLS termination and certificates.

5 years ago, I wouldn’t have been able to tell you what a docker container really was. Thankfully migrating legacy apps to docker on Linux hosts is my full time job and it has allowed me to become proficient enough in a fairly short amount of time.

We all have to start somewhere and shitting on someone for not knowing something now will dissuade them from ever learning it and potentially remove a future contributor to the open source tech stack before they ever even get started.
