Node.js cannot make request to k8s api server - node.js

Question

I'm trying to make an api call to k8s api server to update deployment. I can use below to update deployment.
curl -X PATCH --header "Authorization: Bearer $TOKEN" --insecure -H 'Content-Type: application/strategic-merge-patch+json' --data '
{ "spec": { "template": { "spec": { "containers": [ { "name": "nlu","env": [ { "name": "LAST_UPDATE", "value": "123123" } ] } ] } } } }' \
'https://10.1.0.4:6443/apis/apps/v1/namespaces/prod/deployments/nlu?fieldManager=strategic'
But when I use the node.js request module to make request, I got an error like below
message:"read ECONNRESET"
Here is my code
restart()
{
const options = {
url: "http://10.1.0.4:6443",
body: JSON.stringify({
"spec": {
"template": {
"spec": {
"containers": [
{
"name": "nlu",
"env": [
{
"name": "LAST_UPDATE",
"value": "20190909"
}
]
}
]
}
}
}
}),
auth: {
'bearer': "mytoken"
}
};
return new Promise(function(resolve,reject){
request.patch(options, (err , res)=>{
if(err)
{
reject(err)
} else
{
resolve('done')
}
})
})
}
How can I fix this problem, any help would be appreciated?

Answer 1

I found out I missed something so that the k8s server rejected my request. First, the url should start with https instead of http. Second, I was supposed to add content-type "application/strategic-merge-patch+json" in the request head. Third, I also have to add rejectUnauthorized: false in the request to ignore the error when failing to verify the server's identity.
The correct request should be like
const options = {
url: "https://10.1.0.4:6443",
headers: {
"content-type": "application/strategic-merge-patch+json"
},
rejectUnauthorized: false,
body: JSON.stringify({
"spec": {
"template": {
"spec": {
"containers": [
{
"name": "nlu",
"env": [
{
"name": "LAST_UPDATE",
"value": "20190909"
}
]
}
]
}
}
}
}),
auth: {
'bearer': "mytoken"
}
};
