What does this mean?

Adnan Abdulhussein

See the notes in the agenda side. I want to spend a small amount of time talking about the available containers and how you can run them in Compose, and then transition to explaining how you go from that to production.

Miguel Martinez

Makes sense.To be proper we might want to call it: "Bitnami has container images"

Production-Grade Container Orchestration Platform

Integrates with GCE, AWS, Azure, OpenStack, etc.

Backed by a large open source community

These should be redone to be a little less technical, and more application centric

Example: Kubernetes resourceapiVersion: v1kind: Deploymentmetadata: name: wordpressspec: replicas: 1 template: metadata: labels: app: wordpress spec: containers: - name: wordpress image: bitnami/wordpress:4.7-r0 ports: - containerPort: 80 livenessProbe: httpGet: path: / port: http initialDelaySeconds: 120 timeoutSeconds: 5

Example: Deploying to Kubernetes

$ kubectl create -f ./mariadb-secret.yamlsecret "mariadb" created$ kubectl create -f ./mariadb-deployment.yamldeployment "mariadb" created$ kubectl create -f ./mariadb-service.yamlservice "mariadb" created

$ kubectl create -f ./wordpress-configmap.yamlconfigmap "wordpress" created$ kubectl create -f ./wordpress-deployment.yamldeployment "wordpress" created$ kubectl create -f ./wordpress-service.yamlservice "wordpress" created

$ kubectl create -f ./nginx-deployment.yamldeployment "nginx" created$ kubectl create -f ./nginx-service.yamlservice "nginx" created

Problems with Managing Resources

Boilerplate when developing manifests Upgrades and

configuration changes require manual editing

No history for releases

Difficult to share publicly or with members of your team

Need tooling to hook into release lifecycle

Need a tool to manage a group of resources as a single unit

Package Manager

Charts

(packages)

Are application definitions

Consist of...

Documentation

Live in chart repositories

Why Bitnami Charts?

Optimized images for Kubernetes deployments

Apps kept up-to-date with Bitnami's automated toolchain

A consistent experience, in containers, charts, VMs, etc.

Images kept secure against major vulnerabilities
