– context:
cluster: gke_essch_europe-north1-a_bitrix
user: gke_essch_europe-north1-a_bitrix
name: gke_essch_europe-north1-a_bitrix
You can see something like this:
esschtolts @ cloudshell: ~ / bitrix (essch) $ kubectl config view -o jsonpath = '{. contexts [4]}'
{gke_essch_europe-north1-a_bitrix {gke_essch_europe-north1-a_bitrix gke_essch_europe-north1-a_bitrix []}}
Let's create a new context for this user and cluster:
esschtolts @ cloudshell: ~ (essch) $ kubectl config set-context dev \
> –namespace = development \
> –cluster = gke_essch_europe-north1-a_bitrix \
> –user = gke_essch_europe-north1-a_bitrix
Context "dev" modified.
esschtolts @ cloudshell: ~ / bitrix (essch) $ kubectl config set-context dev \
> –namespace = development \
> –cluster = gke_essch_europe-north1-a_bitrix \
> –user = gke_essch_europe-north1-a_bitrix
Context "dev" modified.
As a result, the following was added:
– context:
cluster: gke_essch_europe-north1-a_bitrix
namespace: development
user: gke_essch_europe-north1-a_bitrix
name: dev
Now it remains to switch to it:
esschtolts @ cloudshell: ~ (essch) $ kubectl config use-context dev
Switched to context "dev".
esschtolts @ cloudshell: ~ (essch) $ kubectl config current-context
dev
esschtolts @ cloudshell: ~ (essch) $ kubectl get pods
No resources found.
esschtolts @ cloudshell: ~ (essch) $ kubectl get pods –namespace = default
NAMEREADY STATUS RESTARTS AGE
Nginxlamp-b5dcb7546-krkm2 1/1 Running 0 10h
You could add a namespace to the existing context:
esschtolts @ cloudshell: ~ / bitrix (essch) $ kubectl config set-context $ (kubectl config current-context) –namespace = development
Context "gke_essch_europe-north1-a_bitrix" modified.
Now create a new cluster in the scope dev (it is now the default, and it can be omitted –namespace = dev ) and removed from the field by default visibility default (it is no longer the default for our cluster, and it is necessary to specify –namespace = default ):
esschtolts @ cloudshell: ~ (essch) $ cd bitrix /
esschtolts @ cloudshell: ~ / bitrix (essch) $ kubectl create -f deploymnet.yaml -f loadbalancer.yaml
deployment.apps "Nginxlamp" created
service "frontend" created
esschtolts @ cloudshell: ~ / bitrix (essch) $ kubectl delete -f deploymnet.yaml -f loadbalancer.yaml –namespace = default
deployment.apps "Nginxlamp" deleted
service "frontend" deleted
esschtolts @ cloudshell: ~ / bitrix (essch) $ kubectl get pods
NAMEREADY STATUS RESTARTS AGE
Nginxlamp-b5dcb7546-8sl2f 1/1 Running 0 1m
Now let's look at the external IP address and open the page:
esschtolts @ cloudshell: ~ / bitrix (essch) $ curl $ (kubectl get -f loadbalancer.yaml -o json
| jq -r .status.loadBalancer.ingress [0] .ip) 2> / dev / null | grep '

Customization
Now we need to change the standard solution to our needs, namely, add configs and our application. For simplicity's sake, we'll mark (change the default) .htaccess file at the root of our application , making it simple to place our application in the / app folder . The first thing that begs to be done is to create a POD and then copy our application from the host to the container (I took Bitrix):
While this solution works, it has a number of significant disadvantages. The first thing is that we need to wait from outside by constantly polling the POD when it will raise the container and we will copy the application into it and should not do this if the container has not been raised, as well as handle the situation when it breaks our POD, external services, can rely on the status of the POD, although the POD itself will not be ready yet until the script is executed. The second drawback is that we have some kind of external script that needs to be logically not separated from the POD, but at the same time it needs to be manually launched from outside, where it is stored and somewhere there should be instructions for its use. And finally, we can have a lot of these PODs. At first glance, the logical solution is to put the code in the Dockerfile:
