-## Danube issues
-
-
-### OPNFV projects' setup.py
-
-- no requirements were installed when calling *python setup.py install* as none of the next keys was set:
- - install_requires
- - tests_require
- - dependency_links
-- shell scripts were not installed neither in $PATH nor in dist-packages
-- all requirements were not synchronized over the OPNFV projects
-
-
-### Functest's Dockerfile
-
-- it copied all the files hosted by the third-party projects (e.g. docs, .git...)
-- several requirements were downgraded/upgraded when building the container as they were managed one after the other
-- it could download packages from [PyPI](https://pypi.python.org/pypi) (e.g. [networking-bgpvpn](https://pypi.python.org/pypi/networking-bgpvpn)...) instead of cloning git repository
-- build dependencies couldn't be removed to save space as it created multiple layers (>70)
-
-
-
-## Management of the requirements
-
-
-### Rely on [pbr](https://docs.openstack.org/developer/pbr/)
-
-- pbr injects requirements into the install_requires, tests_require and/or dependency_links arguments to setup
-- it supports conditional dependencies which can be added to the requirements (e.g. dnspython>=1.14.0;python_version=='2.7')
-
-
-### Split requirements into 3 files
-
-- **requirements.txt** which should list all abstract (i.e. [not associated with any particular index](https://packaging.python.org/requirements/)) dependencies of the OPNFV packages
-- **test-requirements.txt** which could list all abstract dependencies required for testing the OPNFV packages
-- **upper-constraints.txt** which should list all concrete dependencies required by Functest Docker container or the testing virtual environments
-
-
-### Follow [OpenStack requirements management](https://specs.openstack.org/openstack/openstack-specs/specs/requirements-management.html)
-
-- OPNFV (test-)requirements.txt have been updated according to stable/ocata global-requirements.txt.
-- Functest simply use (and complete) stable/ocata upper-constraints.txt in Docker files and tox configuration (testing virtual environments).
-
-
-### On the road
-
-- we have fixed lots of hardcoded paths hidden by the previous design
-- some files were outside the python packages
-- lots of (console) scripts added in OPNFV packages to ease the maintenance of Functest testcases.yaml
-

-## Docker slicing
-
-
-### 8 Functest containers
-
-```bash
-$ sudo docker search opnfv |grep functest-
-opnfv/functest-core OPNFV Functest core image
-opnfv/functest-restapi OPNFV Functest restapi image
-opnfv/functest-features OPNFV Functest vnf image
-opnfv/functest-healthcheck OPNFV Functest healthcheck image
-opnfv/functest-smoke OPNFV Functest smoke image
-opnfv/functest-vnf OPNFV Functest vnf image
-opnfv/functest-components OPNFV Functest components image
-opnfv/functest-parser OPNFV Functest parser image
-```
-
-
-### 8 Functest containers
-
-- Alpine 3.6 is now used as base image
-- one container per test suite has been published (5). All of them are built on top of functest-core.
-- Parser is hosted in its own containers (it requires librairies released for OpenStack Pike)
-- a full container is dedicated to our REST API.
-
-Please see [Run Alpine Functest containers](https://wiki.opnfv.org/display/functest/Run+Alpine+Functest+containers)
-
-
-
-## Next steps
-
-
-### Functest and XCI
-
-- the purpose is simply to allow any OPNFV project integrated by Functest to build their own containers on top of opnfv/functest-core
-- it will allow testing one specific change of these OPNFV projects before merging it in tree
-- it induces that all requirements are synchronized between the different OPNFV projects
-
-
-### F-release
-
-- to allow building opnfv/functest-core from a gerrit change (see https://gerrit.opnfv.org/gerrit/#/c/40909/)
-- to split Functest core/ci and the Functest testcases in two separated Python packages
-- to unlink prepare_env.py and tempest/rally
-
-
-### F-release
-
-- to add python3 support for Functest ci scripts (Functest core already supports both versions)
-- to unlink functest-core from others OPNFV projects (mainly releng and snaps)
-- to write a generic Dockerfile using a set of python packages as input
-
-
-### 2 OPNFV project proposals
-
-- requirements, the counterpart of [OpenStack requirements](https://wiki.openstack.org/wiki/Requirements),
-focused on additional OPNFV project needs
-- xtesting which would be derived from Functest (core and ci parts) as proposed in
