Kubernetes training for customer network integration engineers

We offer private, instructor-led training for field and implementation engineers who connect Kubernetes-hosted software to customer networks and platform controls.

Your team knows the product's expected connections. The customer's traffic and trust paths add separate decisions, including DNS, certificates, proxies, policies, and who can change them.

LearnKube uses a representative request path to connect symptoms to mechanisms, permitted investigations, and a precise request to the responsible customer team.

Explain the path before requesting a change

Integrate the application path by mapping endpoints, names, certificates, and proxies, so engineers can identify the customer prerequisites for communication.
Preserve intended controls by validating permitted traffic and trust relationships, so the product works within the customer's network requirements.
Diagnose blocked connections by distinguishing resolution, routing, policy, and application evidence, so the next action targets the failing layer.
Establish change ownership by recording the required control and its owner, so customer and vendor teams can coordinate a justified correction.

The same timeout can conceal different owners and causes

A product request can cross container networking, cluster DNS, ingress, proxies, and customer-managed infrastructure. Network policies govern another part of that path when the cluster supports enforcement. Similar symptoms can therefore require different evidence and owners. Implementation engineers need to locate the failed connection or trust check before proposing a customer configuration change.

I ask which connection failed before accepting a request to open the firewall. A name-resolution error, certificate rejection, and blocked packet need different evidence, and the customer must know which control we want changed.
— Daniele Polencic, LearnKube founder and Kubernetes instructor

Customer task or requirement	Kubernetes decision	Practice
Resolve a product endpoint	DNS names and namespace scope	Inspect a failed lookup
Reach an external dependency	Egress and customer network controls	Trace the connection path
Establish trusted communication	TLS endpoint and certificate chain	Locate a trust failure
Request a network change	Policy scope and control ownership	Prepare supporting evidence

Your team is not alone in customer integration work

Arize's customer-hosted deployment work includes defining infrastructure requirements and investigating networking, configuration, and performance problems. Its support engineers encounter DNS, TLS, proxies, firewalls, and Kubernetes platform controls.

For teams doing this work, we recommend a four-day workshop focused on traffic paths, diagnostic evidence, and customer-owned change boundaries.

A recommended four-day workshop for integration engineers

This proposed agenda uses a sample product with an external dependency. Customer-specific network details shape the example rather than an assumed universal cluster configuration.

Day 1

Workloads and application endpoints

We connect images, Pods, Deployments, Services, and probes to the product's interfaces. You will distinguish a failed process from a failure to reach that process.

Hands-on exercises

Deploy a sample service and identify its required connections.
Compare an application readiness failure with an unreachable endpoint.

Day 2

Configuration and component ownership

You will use Helm and compare Kustomize for environment settings. We trace control-plane, node, and controller responsibilities to distinguish product configuration from platform integration.

Hands-on exercises

Inspect the resources produced by customer-specific values.
Identify the component and owner behind a required traffic integration.

Day 3

DNS, TLS, policies, and routing

We investigate east-west and north-south traffic, ingress, network policies, service mesh use cases, and placement. Each diagnosis ends with a clear explanation of the affected boundary.

Hands-on exercises

Separate a DNS failure from a network-policy denial.
Trace a TLS or proxy problem and identify the evidence needed by its owner.

Day 4

Credentials, state, metrics, and handover

You will examine secrets, storage, autoscaling signals, authentication, and RBAC around the application path. We connect successful checks to a supportable integration record.

Hands-on exercises

Verify dependency access using the workload's intended credentials.
Document the allowed paths, unresolved constraints, and customer support responsibilities.

Your customer networks, product dependencies, and change boundaries can shape the agenda. Get in touch to tailor the workshop to your integration engagements.

Challenge a diagnosis that skips the connection path

When an engineer calls every timeout a firewall problem, the instructor can introduce a DNS or certificate failure. The group can identify the missing evidence and formulate a more useful customer request.

Start with the connections your product requires

Tell us which customer integrations your team delivers, which controls it can inspect or change, and how issues are escalated. We will recommend exercises that connect those boundaries.
