Mongodb connection in Gitlab CI - mongodb

I'm trying to setup Gitlab Continuous Integration to run some test on an app that uses the MERN stack, I need to configure a mongodb so the test can run but I can't
This is my .gitlab-ci.yml file
image: node:latest
stages:
- build
- test
cache:
paths:
- node_modules/
- packages/back-end/node_modules
- packages/front-end/node_modules

services:

- cd packages/back-end
- npm start
- npm test
I have this error on the test stage:

curl request to docker-compose port hangs in travis-ci

Our travis builds have started failing and I can't figure out why. Our app runs in docker-compose and then we run cypress to against it. This used to work perfectly. Now the host port for the web server is just unresponsive. I've removed cypress and am just trying to run curl http://localhost:3001 and it just hangs. Here's the travis.yml. Any suggestions would be highly appreciated. I have tried fiddling for several hours with the docker versions, distros, localhost vs 127.0.0.1, etc to no avail. All of this works fine locally on my workstation.

The logs look like this:

The command "sleep 30" exited with 0.

The command "curl http://127.0.0.1:3001 --max-time 30" exited with 28.
The docker compose logs show nothing suspicious. It's as if the network wasn't set up correctly and docker is not aware of any requests.

CircleCI with Postgres - cannot connect

In my Circle build, I'm trying to use a Postgres container for testing. The test DB will be created automatically, but Python's not finding the DB. Here's my config.yml:
version: 2.1
​
orbs:
python: circleci/python#0.2.1
​
jobs:
build:
executor: python/default
docker:
- image: circleci/python:3.8.0

python3 ./api/manage.py test

​
workflows:

It seems like everything's fine until the tests start:
psycopg2.OperationalError: 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"?
There's no such folder:
ls -a /var/run/
. .. exim4 lock utmp
It looks like psycopg2 defaults to using the UNIX socket, so you'll need to specify the db host as localhost in your connect() call.
Also an aside, but it looks like you're specifying an additional but unneeded Python image. The executor for the job is already set to be python/default so it doesn't seem like the next image circleci/python:3.8.0 is doing anything based on the config you've pasted in.
Some changes in the PGHOST and DATABASE_URL config solved it:

Gitlab CI with Docker images - Flask microservice testing database

I am trying to deploy a Flack app/service which is built into a docker container to Gitlab CI. I am able to get everything working via docker-compose except when I try to run tests against the postgres database I am getting the below error:
Is the server running on host "events_db" (172.19.0.2) and accepting
TCP/IP connections on port 5432?
Presumably this is because the containers can't see each other. I've tried many different methods. But below is my latest. I have attempted to have docker-compose spin up both containers (just like it does on local), run the postgres db as a git lab service, run from a python image instead of a docker image, use a docker.prod.yml where I remove the volumes and variables.
Nothing is working. I've checked just about every link that shows up on google when you look for 'gitlab ci docker flask postgres' and I believe that I am massively misunderstanding the implementation.
I do have gitlab runner up and going.

What is the executor type of your Gitlab Runner?
If you're using the Kubernetes executor, add this variable:
DOCKER_HOST: tcp://localhost:2375/
For non-Kubernetes executors, we use tcp://docker:2375/
DOCKER_HOST: tcp://docker:2375/
Also, the Gitlab Runner should be in "privileged" mode.
More info:

Hope that helps!

CircleCI Swift with Postgres connection issues

I am working with my repo to build a test app for swift with circleCI and postgres but when it comes to testing I can't seem to grasp how to connect the two images in the testing phase.
I am running
circleci local execute --job build
Which should build both the swift and postgres images. I give them both the same env variables I give in the application. However I get this error when trying to run it. In my experience when trying to set up the two docker containers with compose this error was showing up when my api could not connect to the db container over the network.
Test Case 'AppTests.RemoveUserTest' started at 2019-04-09 19:46:15.380
Fatal error: 'try!' expression unexpectedly raised an error: NIO.ChannelError.connectFailed(NIO.NIOConnectionError(host: "db", port: 5432, dnsAError: Optional(NIO.SocketAddressError.unknown(host: "db", port: 5432)), dnsAAAAError: Optional(NIO.SocketAddressError.unknown(host: "db", port: 5432)), connectionErrors: [])): file /home/buildnode/jenkins/workspace/oss-swift-4.2-package-linux-ubuntu-16_04/swift/stdlib/public/core/ErrorType.swift, line 184
I know it says it failed because of a try statement but that try statement is failing because it's requesting actions from Postgres which is not there. Any ideas?

You're setting the hostname for the database to db, but not defining that anywhere. You need to name your Docker container to match the DB_HOSTNAME environment variable like so https://github.com/vapor/postgresql/blob/master/circle.yml#L8

can`t link mongo docker container

I have an image (gepick:latest) with node app created from Dockerfile:
FROM centos:7
# Create app directory
WORKDIR /usr/src/app
RUN curl --silent --location https://rpm.nodesource.com/setup_8.x | bash -
RUN yum install -y nodejs
RUN curl --silent --location https://dl.yarnpkg.com/rpm/yarn.repo | tee /etc/yum.repos.d/yarn.repo
RUN rpm --import https://dl.yarnpkg.com/rpm/pubkey.gpg
RUN yum install -y yarn
RUN yarn
COPY . .
EXPOSE 8080
CMD [ "yarn", "test-matches-collecting-job"]
My goal is run tests in docker. But it requires mongodb
docker run gepick:latest :
...
Mongoose default connection error: MongoError: failed to connect to server [localhost:27017] on first connect [MongoError: connect ECONNREFUSED 127.0.0.1:27017]
...
I tried link mongo:4 images container docker run --link 0d24c3a35d5a gepick:latest but get same error.
When you launch your container using a docker-compose yaml file Docker bridges the containers together and allows you to have it launch the mongo container before other containers which rely on mongo to be active ... try something like this
cat my-docker-compose.yml
version: '3'
services:
my-gepick:
image: gepick:latest
container_name: blah_gepick
restart: always
depends_on:
- loudmongo
volumes:
- /cryptdata5/var/log/blobs:/blobs
- /webapp/enduser/bundle:/tmp
environment:
- MONGO_SERVICE_HOST=loudmongo
- MONGO_SERVICE_PORT=$GKE_MONGO_PORT
- MONGO_URL=mongodb://loudmongo:$GKE_MONGO_PORT/test
- METEOR_SETTINGS=${METEOR_SETTINGS}
- MAIL_URL=smtp://support#${GKE_DOMAIN_NAME}:blah#loudmail:587/
links:
- loudmongo
ports:
- 127.0.0.1:3000:3000
working_dir: /tmp
command: /usr/bin/supervisord -c /etc/supervisor/conf.d/supervisord.conf
loudmongo:
image: mongo
container_name: loud_mongo
restart: always
ports:
- 127.0.0.1:$GKE_MONGO_PORT:$GKE_MONGO_PORT
volumes:
- /cryptdata7/var/data/db:/data/db
so your launch sequence may look like
docker-compose -f /somedir/my-docker-compose.yml pull
docker-compose -f /somedir/my-docker-compose.yml up -d
