VERSION ==>                       #0.2.0

GOAL ==>                          #Template system using ENVVAR for Docker containers

ALTERNATIVES ==>                  #  - dockerize: simple, only ENVVAR
                                  #  - docker-gen (preferred): many Docker info, can regenerate and fire trigger on change


CMD|ENTRYPOINT dockerize ...      #Instead of CMD|ENTRYPOINT ... in Dockerfile

-template HOST_FIL[:CONTAINER_FIL]#Generate CONTAINER_FILE (def: stdout) using HOST_FILE, when container is run
                                  #HOST_FILE is Go template, using as data OBJ:
                                  #  - OBJ.Env are currently available ENVVAR
                                  #  - adds some FUNC: default, contains, exists, split, replace, parseUrl, atoi, add, isTrue, lower|upper, jsonQuery
-delims STR                       #Change template delimiters
-stdout|stderr FILE               #When container is run, redirect's container's FILE to host's stdout|stderr

-wait URI                         #Wait on URI success. Can be tcp[4|6] or http[s]
-wait-http-header "VAR:VAL"       #
-timeout NUM                      #Timeout for -wait (def: 10, in secs)
-poll                             #Use polling instead of hardware interrupts
