* Update README.md in docker/alpine
- Replace contents with the usage of the image auto-built by Docker Cloud
- Add descriptions on the customizable environment variables
* Update Dockerfile maintainer list
Refer to #1914
* Install rng-tools as runtime dependency
* Remove unnecessary 'git submodule update', as Docker Cloud runs 'git submodule update' after cloning the repository
* Replace variable SERVER_PORT with fixed port 8388, as it can't be customized with -e anyway
* Use the repository as context, instead of released .tar.gz
* Remove version information from Dockerfile, and let Docker Cloud handle it
* Add .dockerignore
Next steps:
1. Connect repository in Docker Cloud
2. Setup automated builds:
- A push on `master` branch triggers build for `unstable` tag
- A tag matching /^v[0-9]+(\.[0-9]+){2}$/ triggers build for a same-named tag
Refer to #1914
Add a new option, WITH_EMBEDDED_SRC, which default is ON and same as
current setting.
When set to OFF, it can use system's libcork, libcorkipset, and libbloom.
It can be built in debian by:
$ cmake -DUSE_SYSTEM_SHARED_LIB=1 -DWITH_STATIC=OFF -DWITH_EMBEDDED_SRC=OFF
$ make
It's possible that c-ares calls the callback function immediately in ares_gethostbyname, which may free the server
structure in that callback function.
Alpine 3.7 libtool pkg depends on bash pkg, this caused the compile hangs at "checking that generated files are newer than configure...", after check [this thread](https://forums.docker.com/t/problem-of-hanging-autoreconf/41015/3), I remove libtool and it works.
