Docker Cheat Sheet

Why

Why Should I Care (For Developers)

"Docker interests me because it allows simple environment isolation and repeatability. I can create a run-time environment once, package it up, then run it again on any other machine. Furthermore, everything that runs in that environment is isolated from the underlying host (much like a virtual machine). And best of all, everything is fast and simple."

TL;DR, I just want a dev environment

Easy handle interface

Options

• CURLOPT_DNS_CACHE_TIMEOUT: controls the TTL of a DNS cache entry. The default is 60s. Use -1 to keep the entry forever.
• CURLOPT_RESOLVE: pre-populate the DNS cache manually.
• CURLOPT_DNS_SERVERS: use alternate DNS servers (instead of system default ones). Warning: works only with c-ares (and it requires c-ares version >= 1.7.4),
• CURLOPT_DNS_USE_GLOBAL_CACHE: cache DNS queries between easy handles. Warning: this is not thread-safe and documented as deprecated. Use the share interface instead (see below).
