SIG-Apps Update Michelle Noorali, SIG-Apps co-lead

We’re growing up so fast!

Time flies when you’re having fun... ● May 9th - initial meeting about creating SIG-Apps ● May 18th - 1st SIG Apps meeting ● 42 SIG-Apps meetings, 2 in-person ● 42 technical demos ● Many discussions, presentations, surveys

Why SIG-Apps? ● Up until now, ○ Understand how to define, install, and manage applications in Kubernetes ○ Talk about & iterate on higher level tools for Kubernetes ○ Keep up with Kubernetes workloads features & improvements ○ Provide feedback on apps experience ○ Friendly place to start k8s journey

● Workloads features and improvements ○ Done ■ Daemon Set Update functionality in 1.6 ■ Deployment/Replica Set bug fixes 1.6 ■ Moved Deployment to Apps API Group ○ Current or In progress ■ Switch Deployments to new hashing algorithm w/ collision avoidance ■ Moving CronJob to beta ■ Fixing flaky tests ■ Stateful Set ● Update functionality (similar to Daemon Set Update) ● Roadmap for GA ● Bug fixes

SIG-Apps houses several umbrella projects.

● Helm ○ Kubernetes package manager ○ Officially graduated from Kubernetes incubator in February 2017 ○ Latest release 2.4.1, growing community ○ Gifted 2 slack channels: #helm-users, #helm-dev ○ Growing pains (note: these should sound familiar) ■ Keeping up with answering questions ● Kudos to the community for jumping in ■ Contributing process ● Pairing with new contributors ● How do you allow community members not on the core team assign issues to themselves? ■ CircleCI woes ■ Figuring out core team processes ■ Outgrowing documentation: efforts to make this better

● Kompose ○ Tool for moving from docker-compose to Kubernetes ○ Latest release 0.6.0, monthly releases ○ Making progress with implementation of docker-compose 'build' ■ Might be ready for next release ○ Still in incubator, close to graduation

● App Registry (previously CNR) ○ Initially a spec for push, pull, discovering Kubernetes Apps ■ Designed to be integrated into different platforms ○ Officially released by CoreOS at CloudNativeCon/KubeCon EU in March ○ Push, pull, and discover Kubernetes apps through Quay ○ Helm plugin available ■ Login to Quay ■ Push charts to Quay ■ Install charts from Quay ○ Working on Quay UI Integration ○ Working on Kompose integration

● Official Kubernetes/Charts repository ○ 70 stable charts, 9 incubator charts, 70+ open PRs for new or improved charts ○ Facing & figuring out scaling challenges ○ Focusing on and highlighting best practices ○ KubeApps.com for searching through charts ■ Built using github.com/helm/monocular

● AppController ○ Install/upgrade/delete Kubernetes resource in pre-defined order, with parent-child hierarchy ■ Creating resource graphs ○ Focus is on complex deployment ○ Led by Mirantis ○ Working on Flow - way to reuse subgraphs as atomic components in multiple releases ○ Adding more examples ○ Improving documentation ○ Helm integration moving forward ■ Created ability to have pluggable release backends in Tiller (called Rudder) ○ AppController demo + Q&A at SIG Apps May 22

● OpenCompose ○ Higher level abstraction for Kubernetes resources

Key Interests & Activities ● Still doing short technical demos of tooling ● Umbrella Projects ○ Mentioned on previous slides ● Kubernetes workloads features & improvements ● Writing less YAML ○ OpenCompose ○ Common Chart (Helm) ○ kube.libsonnett

Logistics ● Alternate between two meeting formats ○ demo + standups ○ demo + discussion topic ● Still meeting weekly

Going forward...

Adnan Abdulhussein Newest SIG-Apps co-lead; Engineer @ Bitnami; Charts repository maintainer; Todo app demo expert

Adding and Iterating ● More discussion around best practices & patterns ● Set better context around demos and discussions ● Good solid feedback loops ● More detailed notes ● Feeling out meeting formats
