Our mission

In a recent NGINX survey [Finding #7], the “biggest challenge holding back developers”

• Having to constantly trade-off between quality of code and expected speed of delivery

• Multiple and increasingly complex environments • Lack of automation tools and processes

4

To solve problems for Developers building cloud-native applications as “services” in containers.

Target users: Modern “2 pizza” development teams

Business process

Teams should be built around business value

5

Microservices

Business activity

Taxonomy – Modern Application Development & Delivery

– Applications or Systems are set of “services”

– “Service” = business value

– Cloud-native is a design pattern

– Microservices is an architecture – Containers are portable. “If it works on my machine, it will run in production” is real

– Platform to deploy “services” (PaaS)

– Infrastructure to run “services (IaaS) – Developers don’t care how

– Serverless is compute on-demand

– DevOps is a practice – App Transformation and DevOps are two sides of the same coin

6

DevOps goal: Maximize business value by reducing cycle time Time value of money principle applied to software delivery

Feel the need for speed

Balancing Time Value of Money

– Time value of delivery

– Time value of shipping

Reducing cycle time minimizes risk, improves quality, speed

VS.

Faster release cycle Less code to validate Easier to schedule

Longer test cycles

Less predictability

Unable to adapt to change

Tugbot—in-cluster testing framework for Docker ContainersDevelopers IT Operations

Use cases—make continuous testing real (24x7x365)

– Simplify & standardize testing in any environment – Any test, Any tool (integration, functional, performance, security, chaos, etc.)

– E.G test backing services or based on operational activities

– Event driven testing - trigger tests on events – Docker events:image update, new container, etc. – Timer events: CRON – once in time interval – Host events: kernel update, host restart, package update, config

update, etc. – External event: someone asked to run tests, etc.

– Standardize collection of test results from all machines – Aggregate and analyze test results over time to track quality improvements – Test context: Events, Docker containers, Host configuration, user defined context

– Share “Test Containers” – ”Social-testing” (e.g. Docker security bench test)

“Tugbot” workflow

KibanaTest

containers

1. Discover test containers

4. Publish results to ES

3. Collect rresults

2. Runtests (Tugbot)

5. Visualize

Example - “test container” Dockerfile.xxx

LABEL tugbot.event.docker=[list of Docker events]

Demo flow

– Deploy app

– Deploy Tugbot services – Run, collect, result – Elasticsearch + Kibana

– Launch app – Vote

– Deploy 1st run of Tugbot

– Inject failures – Functional and integration

– View results

– Inject chaos (Pumba)

– View results
