I'm using traefik v2 as gateway. I have a frontend container running with host https://some.site.com which powered by traefik.
Now I have a micro-service server with multi services and all of them are listening on 80 port. I want to serve the backend server on path https://some.site.com/api/service1, https://some.site.com/api/service2 ...
I have tried traefik.http.routers.service1.rule=(Host(some.site.com) && PathPrefix(/api/service1)) but not worked and traefik.http.middlewares.add-api.addprefix.prefix=/api/service1 not worked too;
How can I implement this?
Can you post your services' docker-compose configuration?
If you use middlewares, you may need to specify the service. Like
traefik.http.routers.service1.middlewares=add-api
traefik.http.middlewares.add-api.addprefix.prefix=/api/service1

I’m using strapi v4 along with the prometheus plugin and right now my app metrics are being exposed on http://localhost:1337/api/metrics
But I need it to be on another port like http://localhost:9090/metrics (also removing the api prefix).
So strapi and the rest of the backend would still be running on port 1337 and only the metrics on 9090
I've been through the documentation but it seems like there is no configuration for that. Can anybody help think of a way to do this?
Right now the metrics don't run on a separate server. They run on the same server as strapi.
This is to be able to use the user-permissions plugin and the API token of strapi to secure the endpoint.
In the future, I could look into making it an option to create a separate server.
According NextJs Documentations:
You should not use fetch() to call an API route in getServerSideProps. Instead, directly import the logic used inside your API route. You may need to slightly refactor your code for this approach.
Fetching from an external API is fine!
So we cannot use NextJs built-in APIs in getStaticProps or getServerSidePropsbut when I'm going to use another API service that is based on Laravel Framework as the back server and fetch it by Axios on the getServerSideProps function, I get Error: connect ECONNREFUSED 127.0.0.1:8080 error.
It should also be noted that everything is fine if the API server is addressed out of our development machine. In Other words, It will face when it's the development environment and both Laravel backend server and NextJs front-end server locate at localhost.
Could you help me out finding a solution for this problem?
When using localhost or 127.0.0.1 inside a docker container, that points to that docker container only, not the host computer.
There are two pretty easy solutions.
Create a docker network, add both containers to that, and use container name instead of ip (https://www.tutorialworks.com/container-networking/)
Use host networking for this container: https://docs.docker.com/network/host/
Edit: Added a link for a tutorial on how to create and use docker networks
So, as #tperamaki's answer already mentions: "When using localhost or 127.0.0.1 inside a docker container, that points to that docker container only, not the host computer."
You can use the ip of your machine in your local network. By example, 196.168.0.10:8080 instead 127.0.0.1:8080.
But you also can connect to the special DNS name host.docker.internal which resolves to the internal IP address used by the host.
In your case just add the port where the othe container is listening:
http://host.docker.internal:8080
In this section of the documentation Networking features in Docker Desktop for Mac, they explain how to connect from a container to a service on the host. Note that a mac is mentioned there, but I tried it on a linux distro and it also works (also in this other answer it is mentioned that it works for windows).
My Spring app uses lets encrypt and is https only. I did not include http to https thing, as it worked for me in postman with https:// format
When I deployed to Cloud Run, and mentioned the custom port (the port specified in spring)
and tested using URL from dashboard
https://..blah..run.app
I am getting error/message
Bad Request
This combination of host and port requires TLS.
What configuration is required on Cloud Run to resolve this?
The url as I see on service details page has htpps://...
EDIT:
If Cloudrun does not need me to take case of SSL, I can remove the application properties entries
server.ssl.key-store-type=PKCS12
server.ssl.key-store=classpath:key/keystore.p12
server.ssl.key-store-password=${lets.secret}
server.ssl.key-alias=someCertAlias
server.ssl.enabled=true
So Can I get an answer on whether to remove SSL from spring?
If cloudrun always uses http, all my calls use redirectConnector, which seems pointless
The Cloud Run Service listens on HTTP and HTTPS. Your application running in the container must listen on a port configured with HTTP only.
FYI: For a public facing web server, you should almost always enable HTTP. Otherwise, when a user enters www.example.com in the browser, the user will receive a connect error. This not always the case, for example .dev gTLDs, but is good practice. When a user connects to Cloud Run with the HTTP protocol, Cloud Run will redirect the user to HTTPS and connect to your application using the HTTP protocol.
I have laravel-backend which only provide api and vue-fontend which connected with that laravel-backend api . It's works locally fine.
But how to configure them in a single(both in same) live server(also with single domain).
Font-end is SPA. i create the font-end using "vue init webpack-simple my-project" commend.
You could use a different port for your api
By doing this you can run both applciations on the same server and access them by specifing the port in the url.
If you don't want to use ports in the url itself, you can also use nginx (or apache i suppose) with reverse proxy to give a 'path' to that port (would also be cleaner)
I am learning Kubernetes on GCP
So far i have two deployments front end and backend as separate containers through separate deployment yaml files.
I am exposing them through service yaml files on port 8080 and 8081 respectively.
I can trigger the endpoints separately , however what should be the hostname/ ip address in the ajax call ?
When I do kubectl get services.
I get two different services with their own cluster ip and external ip , but external ip changes as I delete the service.
how can i use locahost:8081?querysearch in my ajax call
Found the answer.
I was trying something stupid , I had made my ui as a static frontend , hence the need for ajax calls to the backend.
I changed it by using a simple express server serving the requests , and a function inside would call the request to my backend
since the express server is inside the cluster , I was then able to access the backend with
http://service-name.default.svc.cluster.local:portname
