* Add support for reading peer passwords via a file
Syntax of the file is the same as for --peer-router-passwords, that is,
a comma separated list of base64 encoded passwords.
Passwords specified with --peer-router-passwords have precedence over
passwords read from peer-router-passwords-file.
* fix(options): peer password file linting and doc
Co-authored-by: Jean Raby <jean@raby.sh>
* fact(network_policy): validate ClusterIP CIDR
Ensure that --service-cluster-ip-range is a valid CIDR while controller
is starting up.
* fix(network_policy): parse/validate NodePort
Validate the NodePort range that is passed and allow for it to be
specified with hyphens which is what the previous example used to show
and is more cohesive with the way NodePort ranges are specified when
passed to the kube-apiserver.
* test(network_policy): add tests for input validation
* feat(network_policy): permit ExternalIP on input
fixes#934
* fix(network_policy): ensure pos with index offset
Because iptables list function now appears to be returning -N and -P
items in the chain results, we need to account for them when taking into
consideration the rule position.
* fix(network_policy): add uuid to comments on ensure
iptables list is now no longer keeping the position of parameters which
means that we can't compare string to string. In absence of a better way
to handle this, this adds a UUID to the comment string which can then be
looked for when determining what position a rule occupies.
* whitelist traffic to cluster IP and node ports in INPUT chain to bypass
netwrok policy enforcement
Fixes#905
* fix unit test failure
* ensure netpol firewall rules are configured after service proxy firewall rules
* Added flag and condition for open input on iptables #797
* Adding flag to docs.
* Updated to remove INPUT/CHAIN entirely. Name changed to IpvsDenyAll.
* Updated README.
* Updated docstring on ipvs-deny-all
* ipvsDenyAll -> ipvsPermitAll
* Updating user guide.
* Descriptions updates per review
GoBGP's default value for deferral time is 360 seconds.
That means that the routes are not sent to the BGP peer until
this timer is elapsed, so a server is unreachable for 360
seconds, when kube-router restarts.
The new parameter is --bgp-graceful-restart-deferral-time duration_with_unit
For example '--bgp-graceful-restart-deferral-time 10s'
* update netlink
* update libnetwork to get ipvs stats
* update gopkg.lock for libnetwork update
* update libnetwork
* add cli options
* make endpoints delete gracefully
* move conntrack flusher
* get some order in the mainloop
* update to alpine 3.9 & go 1.11.1
* revert to 1.10.3 just update alpine
* and revert travis.yml
* lock version
* test 1.12
* test
* Introduces the option --full-overlay, to always generate IPIP tunnels regardless of node subnets
* Use --overlay-type={subnet,full} instead of --full-overlay={true,false}
When the number of nodes in a cluster is high enough, the
`disableSourceDestinationCheck()` logic creates a high number
of requests to EC2, resulting in throttling and subsequent
problems, such as the inability to attach EBS volumes. This is
not necessarily mitigated by the `ec2IamAuthorized` attribute
which was added to overcome this issue, as the number of
requests can still be high enough to reach Amazon's request
limits. In addition, it is not necessary to run this multiple
times in a loop for all the nodes in a cluster, as it is
sufficient to set it once when an instance boots.
This CLI option allows an administrator to turn off this
feature for kube-router so they can use some other means of
setting the attribute.
* Introduced new cmdline flag --bgp-port, which controls BGP Server listening port and remote port of in-cluster node peers
* Introduced new cmdline flag --peer-router-ports, which controls remote BGP port for external peers
* Introduced new node annotation kube-router.io/peer.ports with same effect as --peer-router-ports
* Introduces the option --override-nexthop, setting it to true will make
advertised next hop for the routers to the peers will be automatically
selected to be appropriate reachable local IP. This will be overrider
any next-hop set for the routes in the RIB. Kube-router by defauly set
the next-hop to `node IP` which is not correct in case of nodes with
multiple interfaces and use differnt interaces for differect external
peers.
Fixes#480
* add next-hop-self documentation
* Node should advertise its pod CIDR to external BGP peers only if
--advertise-node-pod-cidr is set to true (defaults to true).
This is to enable a case where pod's remain non-routable from out of the
cluster but service VIP's can be routable from out side the cluster.
* fix unit test
* address review comments
