Docker image is not usable

[MartinMikita]

Clear build using Dockerfile results in not properly set environment variable IMAGESEARCH_DB, which results in throwing exception basic_string::_S_construct null not valid.

When I switched Dockefile into using nginx instead of lighttpd with correctly set IMAGESEARCH_DB variable, than I am receiving errors System exception: Cannot map file into shared memory: \/shared\/dhash from URL v1/searchIdentical?blockHash=ffff816180a18239c731a381e087b8cf883df971dc01bc858003800dd80fffff&dHash=2592989844c4e0d8

I tried following this exception, which results in failing function ::mmap(const_cast<void*>(addrHint), _size, access, MAP_SHARED, _fd, 0); (poco/Foundation/src/SharedMemory_POSIX.cpp:105)
with errno set to EINVAL (22, Invalid argument)
called by new Poco::SharedMemory(*data_fd, Poco::SharedMemory::AM_READ) (fcgi/MemoryManager.cpp:125)
called by MemoryManager::getData(HashType hashType) (fcgi/HashManager.cpp:114)

How is this docker image used on domain http://imagesearch.mzk.cz/?

Have you tried to point IMAGESEARCH_DB to the file from the release: https://github.com/moravianlibrary/imagesearch.mzk.cz/releases?

@michalbecak could you please comment here?

Well, it is weird, but after downloading imagesearch.db from the release, everything is working.
But this docker image should be working also with empty DB, or at least create some data necessary to run. (now it only creates tables)
