Hello,
I'm new to traefik, and I can't figure why my configuration do not work as expected.
Here is the context :
- 2 front-end app, builded and copy/pasted into a nginx folder using Dockerfile
- 1 rest api, compiled and running with node using Dockerfile
- 1 postgres database and pgadmin
- 1 mongo database and mongo-express.
All of this is setup in a docker-compose.
Frontend Dockerfile:
FROM node:lts-alpine as build
WORKDIR /app/frontend-app1 -- frontend-app2 for the other
COPY package*.json ./
RUN npm install
COPY . ./
RUN npm run build
FROM nginx:alpine
COPY nginx/default.conf /etc/nginx/conf.d/default.conf
COPY --from=build /app/frontend-app1/build /usr/share/nginx/html/frontend-app1
EXPOSE 3001 -- 3002 from frontend-app2
CMD ["nginx", "-g", "daemon off;"]
API Dockerfile:
FROM node:14-alpine
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build
ARG NODE_ENV=qual
ENV NODE_ENV=${NODE_ENV}
EXPOSE 3000
CMD ["node", "dist/main"]

And my traefik config is simple since I can't manage to make it work in without tls.
global:
sendAnonymousUsage: false

docker:
endpoint: "unix:///var/run/docker.sock"

api:
dashboard: true
entryPoints:
web:
address: ":80"
# http:
# redirections:
# entryPoint:
# to: "websecure"
# scheme: "https"
# permanent: true
websecure:
address: ":443"
# http:
# tls:
# certResolver: "letsencrypt"
# certificatesResolvers:
# letsencrypt:
# acme:
# email: "xxx"
# storage: "/letsencrypt/acme.json"
# tlsChallenge: {}
I figure out to make traefik.my_domain.com to work and to log using basic auth.
I can also navigate throught my differents services using localhost:<PORT_BINDED>
But as soon as I want to reach, for example, a front end app, I get a Gateway timeout and can't manage to make it work if I don't specify the port.
For example, accessing to the frontend app which is related to the consultant service:
consulltant-qual.xxx.com result in a gateway timeout, but if I ask consulltant-qual.xxx.com:3001, I can access to my app.
Any help would be grateful,
Thanks
