All file paths are relative to the 'web' docker container, not the host environment. To pass files
to/from the host system for commands that require it ('execfile', 'export', 'import', etc), you may
specify a 'SENTRY_DOCKER_IO_DIR' environment variable to mount a volume for file IO operations into
the host filesystem. The default value of 'SENTRY_DOCKER_IO_DIR' points to '~/.sentry/sentry-admin'
on the host filesystem. Commands that write files should write them to the '/sentry-admin' in the
'web' container (ex: './sentry-admin.sh export global /sentry-admin/my-export.json').
