DEVSTACK sur Ubuntu 20.04 LTS

Workaround à faire avant de lancer le stack.sh :

apt install iptables arptables ebtables
update-alternatives --set iptables /usr/sbin/iptables-legacy || true
update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy || true
update-alternatives --set arptables /usr/sbin/arptables-legacy || true
update-alternatives --set ebtables /usr/sbin/ebtables-legacy || true

Sinon erreur avec broute qui doit utiliser nft.

Fichier de configuration pour devstack local.conf :

# Sample ``local.conf`` for user-configurable variables in ``stack.sh``

# NOTE: Copy this file to the root DevStack directory for it to work properly.

# ``local.conf`` is a user-maintained settings file that is sourced from ``stackrc``.
# This gives it the ability to override any variables set in ``stackrc``.
# Also, most of the settings in ``stack.sh`` are written to only be set if no
# value has already been set; this lets ``local.conf`` effectively override the
# default values.

# This is a collection of some of the settings we have found to be useful
# in our DevStack development environments. Additional settings are described
# in https://docs.openstack.org/devstack/latest/configuration.html#local-conf
# These should be considered as samples and are unsupported DevStack code.

# The ``localrc`` section replaces the old ``localrc`` configuration file.
# Note that if ``localrc`` is present it will be used in favor of this section.
[[local|localrc]]

# Minimal Contents
# ----------------

# While ``stack.sh`` is happy to run without ``localrc``, devlife is better when
# there are a few minimal variables set:

# If the ``*_PASSWORD`` variables are not set here you will be prompted to enter
# values for them by ``stack.sh``and they will be added to ``local.conf``.
ADMIN_PASSWORD=nomoresecret
DATABASE_PASSWORD=stackdb
RABBIT_PASSWORD=stackqueue
SERVICE_PASSWORD=$ADMIN_PASSWORD

# ``HOST_IP`` and ``HOST_IPV6`` should be set manually for best results if
# the NIC configuration of the host is unusual, i.e. ``eth1`` has the default
# route but ``eth0`` is the public interface.  They are auto-detected in
# ``stack.sh`` but often is indeterminate on later runs due to the IP moving
# from an Ethernet interface to a bridge on the host. Setting it here also
# makes it available for ``openrc`` to include when setting ``OS_AUTH_URL``.
# Neither is set by default.
#HOST_IP=w.x.y.z
#HOST_IPV6=2001:db8::7

# Logging
# -------

# By default ``stack.sh`` output only goes to the terminal where it runs.  It can
# be configured to additionally log to a file by setting ``LOGFILE`` to the full
# path of the destination log file.  A timestamp will be appended to the given name.
LOGFILE=$DEST/logs/stack.sh.log

# Old log files are automatically removed after 7 days to keep things neat.  Change
# the number of days by setting ``LOGDAYS``.
LOGDAYS=1

# Nova logs will be colorized if ``SYSLOG`` is not set; turn this off by setting
# ``LOG_COLOR`` false.
#LOG_COLOR=False

# Using milestone-proposed branches
# ---------------------------------

# Uncomment these to grab the milestone-proposed branches from the
# repos:
CINDER_BRANCH=stable/stein
GLANCE_BRANCH=stable/stein
HORIZON_BRANCH=stable/stein
KEYSTONE_BRANCH=stable/stein
KEYSTONECLIENT_BRANCH=stable/stein
NOVA_BRANCH=stable/stein
NOVACLIENT_BRANCH=stable/stein
NEUTRON_BRANCH=stable/stein
SWIFT_BRANCH=stable/stein

# Using git versions of clients
# -----------------------------
# By default clients are installed from pip.  See LIBS_FROM_GIT in
# stackrc for details on getting clients from specific branches or
# revisions.  e.g.
# LIBS_FROM_GIT="python-ironicclient"
# IRONICCLIENT_BRANCH=refs/changes/44/2.../1

# Swift
# -----

# Swift is now used as the back-end for the S3-like object store. Setting the
# hash value is required and you will be prompted for it if Swift is enabled
# so just set it to something already:
SWIFT_HASH=66a3d6b56c1f479c8b4e70ab5c2000f5

# For development purposes the default of 3 replicas is usually not required.
# Set this to 1 to save some resources:
SWIFT_REPLICAS=1

# The data for Swift is stored by default in (``$DEST/data/swift``),
# or (``$DATA_DIR/swift``) if ``DATA_DIR`` has been set, and can be
# moved by setting ``SWIFT_DATA_DIR``. The directory will be created
# if it does not exist.
SWIFT_DATA_DIR=$DEST/data

Pour que keystone démarre, il faut installer une version un peu ancienne de werkzeug (du moins pour Stein):

pip3 install werkzeug==0.16.0
