* Problem: Some docs still say to run MongoDB w/ replica set
Solution: Update the relevant docs
* Problem: A docs mention of upsert-validator wasn't linked to BEP-3.
Solution: Link that docs mention to BEP-3 on GitHub.
- Standardize docker-compose workflow
- Change docker-compose version to 2.1
- why one might ask? because compose version
3.0 does not support depends on and inherits
like we want to and is more aimed towards migration to using
`docker stack`, for our current strategy `2.1` is a better choice.
- change `bdb` service `bigchaindb` service
- why? Introduced a new proxy service `bdb` which is just a dummy
`busybox` image.
- why? because this ensure via healthcheck of bigchaindb that BigchainDB
has started properly and makes a `curl` to ensure HTTP API server is up
and running.
- why? Because we have had scenarios where BigchainDB is not started
via docker compose and user has to check out the logs to find out what
the problem might be. This ensure that bigchaindb is up and running.
- Does this change deployment workflow? No.
- The only thing change is that if you want to run commands inside a bigchaindb
container e.g. `pytest` now you have to run the following command:
`docker-compose run --rm --no-deps bigchaindb pytest -v --cov=bigchaindb`
as opposed to `docker-compose run --rm --no-deps bdb pytest -v --cov=bigchaindb`
- Remove env variable `BIGCHAINDB_START_TENDERMINT`
- Remove TENDERMINT_INTEGRATION.rst and move to the new docs
- Change mdb -> mongodb because the other services were named with
full name.
- Add example to run specific tests or from a file
- Update config.toml for tendermint to use `bigchaindb` as proxy app
instead of `bdb`
- Remove `network` directory because it is deprecated
- Add comment about why PYTHONBUFFERED is used
