Get YAML for deployed Kubernetes services?

kubernetes deployment yaml example
kubectl get --export
kubectl get nodes
kubectl get --export
kubectl get events
kubectl jsonpath
kubectl get export deprecated
kubectl commands

I am trying to deploy my app to Kubernetes running in Google Container Engine.

The app can be found at:

The Dockerfile is built into an image on Google Container Registry.

I have deployed the app in Kubernetes via the + button. I don't have the YAML for this.

I have inserted a Secret in Kubernetes for the PEM file required by the app.

  1. How do I get the YAML for the Deployment, Service and Pod created by Kubernetes by filling in the form?
  2. How do I get the Secret into my Pod for usage?

To get the yaml for a deployment (service, pod, secret, etc):

kubectl get deploy deploymentname -o yaml --export

kubectl Cheat Sheet, You've deployed your application and exposed it via a service. kubectl get deployment my-nginx -o yaml > /tmp/nginx.yaml vi /tmp/nginx.yaml� In order to get the yaml for deployment pass the following command. kubectl get deploy <deploymentname> -o yaml --export. if your deployment is not in conventional namespace then . kubectl get deploy --all-namespaces -o yaml --export. for more information on deployments checkout the following video tutorial

How do I get the YAML for the Deployment, Service and Pod created by Kubernetes by filling in the form?

kubectl get deployment,service,pod yourapp -o yaml --export

Answering @Sinaesthetic question:

any idea how to do it for the full cluster (all deployments)?

kubectl get deploy --all-namespaces -o yaml --export

The problem with this method is that export doesn't include the namespace. So if you want to export many resources at the same time, I recommend doing it per namespace:

kubectl get deploy,sts,svc,configmap,secret -n default -o yaml --export > default.yaml

Unfortunately kubernetes still doesn't support a true get all command, so you need to list manually the type of resources you want to export. You can get a list of resource types with

kubectl api-resources

Managing Resources, kubectl get po,deployment,rc,rs,ds,no,job -o yaml? for n in $(kubectl get -o= name pvc,configmap,ingress,service,secret,deployment� This Kubernetes deployment tutorial guide will explain the key concepts in a Kubernetes YAML specification with an Nginx example deployment. Introduction: In Kubernetes, pods are the basic units that get deployed in the cluster. Kubernetes deployment is an abstraction layer for the pods. The main purpose of the deployment object is to maintain the resources declared in the deployment

The same issue is discussed at kubernetes GitHub issues page and the user "alahijani" made a bash script that exports all yaml and writes them to single files and folders.

Since this question ranks well on Google and since I found that solution very good, I represent it here.

Bash script exporting yaml to sub-folders:

for n in $(kubectl get -o=name pvc,configmap,serviceaccount,secret,ingress,service,deployment,statefulset,hpa,job,cronjob)
    mkdir -p $(dirname $n)
    kubectl get -o=yaml --export $n > $n.yaml

Another user "acondrat" made a script that do not use directories, which makes it easy to make a kubectl apply -f later.

Bash script exporting yaml to current folder:

for n in $(kubectl get -o=name pvc,configmap,ingress,service,secret,deployment,statefulset,hpa,job,cronjob | grep -v 'secret/default-token')
    kubectl get -o=yaml --export $n > $(dirname $n)_$(basename $n).yaml

The last script does not include service account.

Syntax for downloading yaml's from kubernetes

kubectl get [resource type] -n [namespace] [resource Name] -o yaml > [New file name]

Create yaml file from running pod:

  1. kubectl get po -n nginx nginx-deployment-755cfc7dcf-5s7j8 -o yaml > podDetail.yaml

Create replicaset yaml file from running pod:

  1. kubectl get rs -n nginx -o yaml > latestReplicaSet.yaml

Create deployement yaml file from running pod:

  1. kubectl get deploy -n nginx -o yaml > latestDeployement.yaml

Introduction to YAML: Creating a Kubernetes deployment, kubectl create -f kubectl get services phpmyadmin NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE phpmyadmin� Now let’s go ahead and create the deployment. Add the YAML to a file called deployment.yaml and point Kubernetes at it: > kubectl create -f deployment.yaml deployment "rss-site" created. To see how it’s doing, we can check on the deployments list:

for the 2nd question regarding the secret, this is from the k8s documentation. see for more info.

  1. Create a secret or use an existing one. Multiple pods can reference the same secret.
  2. Modify your Pod definition to add a volume under spec.volumes[]. Name the volume anything, and have a spec.volumes[].secret.secretName field equal to the name of the secret object.
  3. Add a spec.containers[].volumeMounts[] to each container that needs the secret. Specify spec.containers[].volumeMounts[].readOnly = true and spec.containers[].volumeMounts[].mountPath to an unused directory name where you would like the secrets to appear.
  4. Modify your image and/or command line so that the program looks for files in that directory. Each key in the secret data map becomes the filename under mountPath.

I have used this and it works fine.

5.2 Pod Configuration Using a YAML Deployment, All containers in Kubernetes are scheduled as pods, Lastly, all Kubernetes objects can and should be described in manifests called Kubernetes YAML files. bulletinboard:1.0 --- apiVersion: v1 kind: Service In this case, you'll get just one replica , or copy of your� A Kubernetes YAML file can include the definition of multiple objects - each separated by ---. You can use >> to redirect the output of a command to a file, appending the output to the existing contents of the file. For example, you could append a Service to expose my-deploy in deployment.yaml. Note: You will need to run kubectl apply -f

  • any idea how to do it for the full cluster (all deployments)? The idea being, of course, to create mirror environments with the exact same services.
  • @Sinaesthetic, List exports are not supported so far and don't seem to be coming soon. You will probably need a script to list all ressources then cycle through those ressources to build your list.…
  • As of Kubernetes 1.14, --export is deprecated; see here. You can use get -o yaml without --export, although that includes information about the current object state, as well as the declarative configuration needed to (re)configure the object.
  • Still need to remove some current state from the yaml generated by "-o yaml", for example, spec.clusterIP and metadata.resourceVersion in service.
