Everyone that uses Kubernetes, needs images….
Where do your images come from?
Build them Source them
How much time do you [ want to ] spend on that?

32
Key Finding: There is something holding you back…What is it?
Recall:
• Goal: Reduce Dev Cycle Time
• Goal: Get Developers Focused On Code
ImageFiles Require More Automation
Dockerfiles do not scale…

Popular and easy to get started
Dockerfile: Most common way of creating containers

Confidential │ ©2020 VMware, Inc.
• Dockerfiles are the most common way
of creating Docker Images
• Their flexibility is their power
• Run any command, mutate any file
• Their flexibility is their weakness
• Keeping consistent, ensuring security
• Takes a lot of effort for "good"

Let’s start with a route and understand how the gateway helps me with XCCs
Understanding the Spring Cloud Gateway building blocks
38
Link to Spring Cloud Gateway doc
• Routes define how the Gateway will process incoming requests.
• Each route is composed of Predicates, Filters, and a Service.
• Predicates determine whether the route matches any given
request.
• Filters apply behavior to matching requests or their responses.
• The Service determines where the request will be forwarded after
filtering.

The logic for executing the cross-cutting concerns
How they all work − Spring Cloud Gateway
39
1. Client makes a
request to the
Gateway.
2. Evaluates
Predicates to match
a request to a route.
3. Runs through the “pre” filter logic chain
specific to the request.
Pre-request
Post-request
4. Proxy routes the
request to the service.
Proxied
Service
5. Service is executed.
6. Runs the “post” filter logic.

Evaluate conditions to map requests to a route
Spring Cloud Gateway Predicates
40
• HTTP Method matches a list?
• URI Path matches a pattern?
• URI Query matches a regex?
• RemoteAddr matches CIDRs?
• Weight within a route group
Link to available Predicates
• After a certain datetime?
• Before a certain datetime?
• Between two datetimes?
• Cookie matches a regex?
• Header value matches a regex?
• Host matches a pattern list?

Allow you to do things with requests/responses
Spring Cloud Gateway Filters
41
Link to available Filters
• Add, remove, modify headers; map values; add security headers.
• Rewrite path, extract segments, add / remove prefix.
• Redirect users.
• Retry and use Circuit Breaker.
• Change response status.
• List authorized roles and scopes to access route.

Allows you to limit number of requests
Spring Cloud Gateway – Rate Limiting Filter
42
• The Rate Limiting Filter limits the number of requests
allowed from a route, with the ability to burst the limit to
a max number.
• Duration specified in seconds(s), minutes(m), or hours(h).
• Within limits: response will succeed + report how many
requests can still be made.
• Exceeded limits: fail with 429 Too Many Requests.
• Ex.: Limit users to 2 requests every 5 seconds.

Route filter
Single sign-on authorized endpoint – Security
47
• The SSO-enabled filter will force the client to be
authenticated before allowing access to a route.
• If the client is not authenticated, they will receive a
302 HTTP response with redirect URL to API
Gateway’s configured SSO login page.
• Ex: The /api/adopt route has the SSO-enabled
filter enabled, when accessed through an HTTP
GIT request.

What are the challenges with patching?
Must keep your system up-to-date – regularly update your apps, dependencies, JDK, OS, K8S and Host OS
• Volume of patches & updates
• Securing approvals for delaying
• Scaling coordination between
• App development teams
• DevOps teams
• Re-run pipelines for every change
to container image
• Testing
• Certification
• Staging and
• Deploy to production
• Are pipelines stateless and
reproducible?

BTW: There’s a fresh CVE created every 20 minutes
