-#openstack #network 
-# Schematic on switch network
- ![[Switch-network]]
-# Procedure
-Kevin configures the switches so that the public network is routed to the correct private network and sets up a VLAN.
-
-By now we should have a VLAN tag and a private subnet that will be used, for example we will use VLAN tag 150 as well as subnet 10.8.4.0/2.
-# Make sure VLAN interface exists on network node
-> For new network nodes this is done with Ansible, however for fear of disrupting live traffic we prefer to add additional ones on existing nodes by hand.
-
-Check whether an interface exists on the bond for the given vlan (e.g `bond0.150` given VLAN tag 150).
-
-If not add an entry in `/etc/network/interfaces` so it survives reboots:
-```
-auto bond0.150
-iface bond0.150 inet manual
-  vlan-raw-device bond0
-```
-And then of course we add this interface with `sudo ifup bond0.150` with 150 being the VLAN tag we've been given.
-# Create switch network on openstack
-Define the switch network and OVN mapping in hieradata. Make sure to run Puppet on relevant controllers and network nodes.
-```YAML
-group/os-onecom-os1.yaml
-profile::openstack::neutron::controller::networks:
-  switch-network-vps4-cph8:
-    provider_network_type: flat
-    provider_physical_network: switch-network-vps4-cph8
-    router_external: true
-    shared: false
-    project_id: bb8fd38613c6464e8c00cbc332e2c67d
-
-domain/network.env.vps4-cph8.one.com.yaml
-profile::openstack::neutron::ovn::controller::bridge_interface_mappings:
-  - 'ext-br150:bond0.150'
-profile::openstack::neutron::ovn::controller::ovn_bridge_mappings:
-  - 'switch-network-vps4-cph8:ext-br150'
-```
-
->When adding an external or public network openstack will automatically create a RBAC policy that allows any project to access it. Make sure it is removed: `openstack network rbac list --target-project '*'` will contain an entry with **object type network**. Show it, make sure it's the switch network, and delete it.
-
->The Puppet module used for creating networks assigns the largest possible MTU to a network. We require it to be set to 1500. After changing the MTU to 1500 disable and enable DHCP so that the DHCP server also takes the configuration in effect.
-# Create switch subnets on openstack
-Once that's taken care of we can add the switch subnets to neutron via hieradata, usually a group yaml (e.g `group/os-onecom-os1)
-```yaml
-profile::openstack::neutron::controller::subnets:
-	switch-subnet-vps4-cph8-ipv4:
-	    cidr: 10.8.4.0/24
-	    ip_version: 4
-	    allocation_pools: [ 'start=10.8.4.4,end=10.8.4.254' ]
-	    gateway_ip: 10.8.4.1
-	    network_name: switch-network-vps4-cph8
-	    project_id: bb8fd38613c6464e8c00cbc332e2c67d
-	switch-subnet-vps4-cph8-ipv6:
-	    cidr: 2a02:2350:a:105::/64
-	    ip_version: 6
-	    allocation_pools: [ 'start=2a02:2350:a:105::4,end=2a02:2350:a:105::ffff' ]
-	    gateway_ip: 2a02:2350:a:105::1
-	    network_name: switch-network-vps4-cph8
-	    project_id: bb8fd38613c6464e8c00cbc332e2c67d
-	    ipv6_address_mode: dhcpv6-stateful
-	    ipv6_ra_mode: dhcpv6-stateful
-```
-
-> We want to have AZ reflected in the switch network name as shown in our example above "switch-network-vps4-cph8". Older switch-networks do not yet follow this convention.
-
-> We reserve the first three and last one IP in the pool of a given /24. Hence the allocation pool starts at .4 and ends at .254. These IP's are reserved for routers & switches, for example the .1 is assigned to the gateway.
-
-> When running Puppet on the controller node to create the subnet it can happen that it complains that the subnet overlaps with another. It might be caused because another controller is running Puppet at the same time and it created the subnet before your run.
-
-# Create router on openstack
-`openstack router create --external-gateway switch-network-vps4-cph8 --fixed-ip subnet_id=switch-subnet-vps4-cph8-ipv4,ip-address=10.8.4.4 --fixed-ip=switch-subnet-vps4-cph8-ipv6,ip-address='2a02:2350:a:105::4' --disable-snat switch-network-vps4-cph8`
-# Ensure reverse DNS zone
-We should make sure the reverse DNS zone is added to the `service.g1-dns.one` zone to ensure PTR records can be added via SysAPI.

-Should be via `service.g1-dns.one` rather than `auth`. We can make a ticket in SYSDNS to have it corrected; [example](https://group-one.atlassian.net/browse/SYSDNS-510).

-Takeaways:
-- Minder focus op latest hippe tech gebruiken
-- Eerder om hulp vragen
-- Keep it simple, stupid
-- POP maken samen met Rutger
-- Criteria opstellen voor verschillende niveaus system engineer (junior, medior, senior); focus op senior.
-
----
-Over het algemeen is Rutger blij met me; hij zegt dat ik het goed doe. Hij heeft een aantal verbeterpunten:
-- Wil te veel bleeding-edge tech gebruiken
-- Ik maak het soms te ingewikkeld - te veel lagen abstractie in de backup service API bijvoorbeeld.
-Eerder om hulp vragen; meer team betrekken bij wat ik doe.
-
-Salaris verhoging: 5%
-4358 -> 4575,90
-
-**Huidige rolbeschrijving**
-Mijn huidige rol **Medior Software Engineer**; is niet meer up-to-date. Dit gaat aangepast worden naar **Medior System Engineer**.
-
-Rutger gaf aan dat hij mij nog niet als senior erkent; maar gaf ook toe dat hij dat puur op gevoel doet en er nu niet een duidelijk pad/criteria bestaan om senior te worden.
-
-De vacature "OpenStack Engineer" zoals die op internet staat geeft een bepaald loonsbeeld om mensen aan te trekken; dat is wat bestaande engineers niet meteen krijgen (zelfs Rutger niet).

-I need to become more goal-oriented: set a clear goal with a clear end and work towards that.
-I'm currently working to improve my skill in note-taking to help achieve current and determine new goals.
-I'm doing this by setting up a "second brain" using ideas from the book "Building a second brain" by Tiago Forte.
-
----
-
-**General Performance and Achievements**  
-	Describe your overall performance throughout the year and highlight any achievements you are especially proud of
-
-Looking back I feel that my focus this year has been impacted due to a series of events happening outside of work in my private life, such as moving to a new house and the death of a close friend. Besides that I feel I was often doubting myself which made me indecisive at times.
-
-The backup service which I had mostly worked on developed far slower than I liked. Due to above but also because so many parts of this were completely new to me. I think that I could have done a better job at learning each of them by separating it into smaller "toy" projects and learning each part before putting it together. For example how libraries such as oslo.messaging and taskflow worked. Besides that I also feel I didn't always do a great job on including the rest of the team.
-During the last quarter of this year I did feel I was able to improve and work with a clearer mind and work more closely together with Erik; communicating more frequently and effectively, especially with the snapshots.
-
-I feel proud that, even though it was not progressing as quickly or organized as I liked, I was able to set-up the backup service and put it to production and seeing few operational problems as of yet. I feel especially proud of how we were able to utilize the project to quickly implement the snapshot feature that was suddenly requested.
-
-**Opportunities to become even better**
-	Which areas do you perceive as your strongest?
-
-I think I'm always eager to develop a deep understanding of how things technically work, abstract thinking, I have a sense of responsibility and am always prepared to help out where needed.
-
-	Which areas would you like to improve in?
-
-I am currently trying to improve my productivity by setting up a note taking system. I will continue trying to improve this. I plan to also do a little self "performance review" at the end of each week to help me keep track of things happening during the year.
-
-I think in a broad sense I need to become better at setting clear goals that have a clear end which I can work toward. Both in work related things such as projects, but also in personal things such as setting up a note taking system.
