How easy is to quick test and prototype

Nowadays docker compose is getting life so much easy for developers.

Let's say I want to quickly test some python code on elasticsearch... I just need to have a compose file like the one below, and then from the same directory:

docker-compose up -d

# 1. start with a small image (e.g. alpine OS)
FROM alpine:3.7
# or with the 'alpine' version of the official build
# FROM nginx:1.13.9-alpine
# 2. fix a tag to image version

# 3. Provide info about who you are

B2SAFE <-> B2ACCESS certificates issue

Reproducing the issue with the dockerized environment of the HTTP-API, using the 'debug' mode.

Since iRODS uses thread locks I tried overriding the original session class to make it possible.

Test it with:

import pickle
import base64

original_session = iRODSPickleSession(...)

Simple and lightweight python process LOCK

Use a lock across python processes or threads.

Based on sqlite/sqlalchemy implementation. Tested on python 3.4+.

To see how it works launch process.py multiple times.
