I m new at docker so i tried to connect multiple container
- mongo
- my app
- redis
and i get this error in chrome=> code: "ECONNREFUSED", errno: "ECONNREFUSED", syscall: "connect", address: "127.0.0.1", port: 8080}
here is my docker-compose file :
version: "2"
services:
mongo:
image: "mongo"
restart: always
ports:
- "27017:27017"
networks:
- all
redis:

node:

links:
- mongo
ports:

networks:

backoffice:

- mongo
- redis
depends_on:
- mongo
- node
- redis
ports:
- "8181:8181"
networks:
- all
networks:
all:
driver: bridge
my differents Dockerfile:
for mongo:
FROM mongo:2.6
COPY ./data ./
EXPOSE 27017
CMD ["mongod"]
for service node:
FROM node:4.4.7
WORKDIR /app
COPY /api ./
RUN npm install
RUN apt-get -q update && apt-get install -y -qq \ git \ curl
EXPOSE 8080
CMD ["node","index.js"]
for service back:
FROM node:4.4.7
WORKDIR /api
COPY . ./
RUN npm install && npm install bower -g && npm install gulp -g
RUN bower install --allow-root && gulp build
RUN apt-get -q update && apt-get install -y -qq \ git \ curl
EXPOSE 8181
CMD ["node","index.js"]
can you please help me figure this out ?
Probably your port 8080 is already in use. Open your cmd and type netstat -a. This is for checking the ports availability.
I solve my issue, i was using version 2 of docker-compose but links are available only from version 3.
Just upgrade and it works fine.

for some reason after running this commands:

docker-compose -f docker-compose.yml -f docker-compose.prod.yml up
im getting an error when the bot container running up, that he cant find any node module...
im using ubuntu 20.4 to run docker inside, installed docker and for some reason only this part is not working, wehn im running a build on normal machine without docker, build is working fine.
The only problem is with the docker.

I`m trying to connect to my company's LDAP server to authenticate users in my flask web app. I'm constantly getting this error:
2020-06-22 09:55:07,459 ERROR flask_ldap3_login MainThread : no active server available in server pool after maximum number of tries
I also tried to telnet to the ldap server from the web container and not connection can be made. What do I need to do to allow my containers to run on our network to be able to access LDAP?
I tried enabling SSL and added the certs, but still no success.

I'm trying to connect my Python-Flask app with a Postgres database in a docker environment. I am using a docker-compose file to build my web and db environment.
However, I am getting the following error:
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
Here is my docker file:

After command docker-compose -f docker.yml build evey time I've got an error
Step 5/9 : RUN npm install
---> Running in d3644d792807
/bin/sh: 1: npm: not found
ERROR: Service 'essblockexplorer' failed to build: The command '/bin/sh -c npm install' returned a non-zero code: 127
What am i doing wrong? I found similar issues but i didnt find the real solution for solving this problem
You shouldn't need the mysql image in your Dockerfile at all; ideally your app container (essblockexplorer) accesses the db container (db) via a NodeJS client. All you need to do is;
Remove the FROM mysql:latest line from your Dockerfile.
Access the MySQL database via a NodeJS client using (db) as the hostname (this is automatically loaded as an alias into your container).
I'm new to docker-compose and I'd like to use it for my current development.
after I ran docker-compose up -d everything was starting ok and it looks good. But my nodejs application wasn't installed correctly. It seems like npm install wasn't complete and I had to do docker exec -it api bash to run npm i manually inside the container.
Here's my docker-compose.

Here's my docker-command.sh

# if we want to be interactive with our app container, it needs to run in

tail -f /dev/null

nodemon

Here's my Dockerfile
FROM nodesource/nsolid:latest
RUN mkdir /usr/lib/app
WORKDIR /usr/lib/app
COPY [".npmrc", "package.json", "/usr/lib/app/"]
RUN npm install \
&& npm install -g mocha \
&& npm install -g nodemon \
&& rm -rf package.json .npmrc
In your Dockerfile you are running npm install without any arguments first:
RUN npm install \
&& npm install -g mocha \
This will cause a non-zero exit code and due to the && the following commands are not executed. This should also fail the build though, so I'm guessing you already had a working image and added the npm instructions later. To rebuild the image use docker-compose build or simply docker-compose up --build. Per default docker-compose up will only build the image if it did not exist yet.
