Installing and Running GBP
The following are a set of instructions for installing and working with GBP:
Devstack Installation
For mitaka and beyond (including the master), use the GBP devstack plugin: https://github.com/openstack/group-based-policy/blob/master/doc/source/installation.rst#using-devstack
For Liberty installation use: https://github.com/group-policy/gbp-devstack
After the devstack install is complete, use the "gbp" CLI binary ("gbp --help" will give you the commands)
GBP Basic CLI and Workflow
Example scenario: Modeling connectivity between Web and App Tiers using GBP:
# Create allow action that can used in several rules gbp policy-action-create allow --action-type allow
# Create ICMP rule gbp policy-classifier-create icmp-traffic --protocol icmp --direction bi gbp policy-rule-create ping-policy-rule --classifier icmp-traffic --actions allow
# Create SSH Rule (Optional) # gbp policy-classifier-create ssh-traffic --protocol tcp --port-range 22 --direction bi # gbp policy-rule-create ssh-policy-rule --classifier ssh-traffic --actions allow
# Create HTTP Rule gbp policy-classifier-create web-traffic --protocol tcp --port-range 80 --direction in gbp policy-rule-create web-policy-rule --classifier web-traffic --actions allow
# Create HTTPs Rule gbp policy-classifier-create secure-web-traffic --protocol tcp --port-range 443 --direction in gbp policy-rule-create secure-web-policy-rule --classifier secure-web-traffic --actions allow
# ICMP policy-rule-set gbp policy-rule-set-create icmp-policy-rule-set --policy-rules ping-policy-rule
# WEB policy-rule-set gbp policy-rule-set-create web-policy-rule-set --policy-rules web-policy-rule
# Policy Target Group (PTG) creation gbp group-create web gbp group-create client-1 gbp group-create client-2
# Policy Target creation and launching VMs WEB1=$(gbp policy-target-create web-ep-1 --policy-target-group web | awk "/port_id/ {print \$4}") CLIENT1=$(gbp policy-target-create client-ep-1 --policy-target-group client-1 | awk "/port_id/ {print \$4}") CLIENT2=$(gbp policy-target-create client-ep-2 --policy-target-group client-2 | awk "/port_id/ {print \$4}")
nova boot --flavor m1.nano --image cirros-0.3.2-x86_64-uec --nic port-id=$WEB1 web-vm-1 nova boot --flavor m1.nano --image cirros-0.3.2-x86_64-uec --nic port-id=$CLIENT1 client-vm-1 nova boot --flavor m1.nano --image cirros-0.3.2-x86_64-uec --nic port-id=$CLIENT2 client-vm-2
####CHECKPOINT: No traffic flows
# policy-rule-set Association gbp group-update client-1 --consumed-policy-rule-sets "icmp-policy-rule-set=true,web-policy-rule-set=true" gbp group-update client-2 --consumed-policy-rule-sets "icmp-policy-rule-set=true,web-policy-rule-set=true" gbp group-update web --provided-policy-rule-sets "icmp-policy-rule-set=true,web-policy-rule-set=true"
####CHECKPOINT: ICMP and HTTP work from app to web and vice versa
gbp policy-rule-set-update web-policy-rule-set --policy-rules "secure-web-policy-rule"
####CHECKPOINT: HTTP stops working for both the client PTGs, HTTPs is now enabled
Configuring and testing External Connectivity
Implicit workflow for RMD.
# ADMIN: create default external segment based on the name configured in "default_external_segment_name" # NOTE: in Juno, the RMD requires the Neutron external subnet to pre-exist. gbp external-segment-create default --subnet_id $EXT_SUB_ID --external-route destination=0.0.0.0/0,nexthop= --shared True
# USER (any tenant): create PTG with the normal workflow gbp group-create group-with-external-access
# Create external PTG (called External Policy) gbp external-policy-create [name]
# Provide and Consumes PRS on normal PTGs and EPs gbp group-update group-with-external-access --consumed-policy-rule-sets "web-policy-rule-set=true" gbp external-policy-update [name] --provided_policy_rule_sets "web-policy-rule-set=true" ###HTTP traffic is now enabled towards the external world
Explicit Workflow (old non-external workflow still assumed implicit here):
# ADMIN: create non-default external segment for a given tenant (or shared) # NOTE: in Juno, the RMD requires the Neutron external subnet to pre-exist. EXT_SEG_ID=$(gbp external-segment-create [not-default-name] --subnet_id $EXT_SUB_ID --external-route destination=0.0.0.0/0,nexthop= --shared True | awk "/ id / {print \$4}")
# USER: create PTG with the normal workflow gbp group-create group-with-external-access
# Link the implicitly created L3P to the external segment gbp l3policy-update [l3-policy-id] --external-segment $EXT_SEG_ID=
# Create external PTG (called External Policy) linked to the External Segment gbp external-policy-create [name] --external-segments $EXT_SEG_ID
# Provide and Consumes PRS on normal PTGs and EPs gbp group-update group-with-external-access --consumed-policy-rule-sets "web-policy-rule-set=true" gbp external-policy-update [name] --provided_policy_rule_sets "web-policy-rule-set=true" ###HTTP traffic is now enabled towards the external world
