How to connect travis ci mongodb service from inside docker container? - mongodb

See the logs of: https://travis-ci.com/Jeff-Tian/uni-sso/builds/147317611
I created a travis CI project, that uses mongodb service. And it then runs a docker which from inside will connect that mongodb. But as the log shows, it will fail.
I tried those MONGO_URI, none of them works:
mongodb://localhost:27017
mongodb://127.0.0.1:27017
mongodb://host.docker.internal:27017
Can anyone shed some light on this? I can't find a solution either from Travis CI document nor google.
Thanks in advance!
more details
I can use mongodb://host.docker.internal:27017 in travis ci unit test, but inside the docker it would fail.

Probably already late for you, but I've managed to find solution for the same problem I had here https://docs.docker.com/network/network-tutorial-host/.
This approach binds docker container directly to the Docker host’s network
My script to run tests in docker container:
script:
- docker run --network host -e CI=true mydocker/api-test npm test
Then, from your test you can access mongodb using this url
mongodb://127.0.0.1:27017/mongo_db_name

Concourse CI: Quickstart + localhost

I've just started 'kicking the tires' on Concourse-CI, using the quickstart tutorial as my starting point. That much works fine.
I've created a super basic pipeline with a single task, just like the quickstart tutorial. But instead of pulling the busybox image and executing the echo command, I'm pulling another image, and running a command that would try to update a local postgres db.
When I run the pipeline - my task (docker image writing to local postgres db) fails - because connection can't be made to the local db. I've searched far and wide - and can't seem to figure out how to do this. In the docker-compose from the quickstart tutorial, I've tried adding CONCOURSE_CONTAINERD_ALLOW_HOST_ACCESS: "true" to no avail
Any suggestions on how I may be able to achieve this?
Turns out my issue had nothing to do with Concourse.
The local postgres instance I was attempting to write to was only accepting connections from localhost - which won't allow connections from Docker containers. I updated postgres setting to allow remote connections - and all is well.

requested access to the resource is denied [duplicate]

I am using Laravel 4.2 with docker. I setup it on local. It worked without any problem but when I am trying to setup online using same procedure then I am getting error:
pull access denied for <projectname>/php, repository does not exist or may require 'docker login'
is it something relevant to create repository here https://cloud.docker.com/ or need to docker login in command?
After days of study I am still not able to figure out what could be the fix in this case and what are the right steps?
I have the complete code. I can paste here if need to check certain parts.
Please note that the error message from Docker is misleading.
$ docker build deploy/.
Sending build context to Docker daemon 5.632kB
Step 1/16 : FROM rhel7:latest
pull access denied for rhel7, repository does not exist or may require 'docker login'
It says that it may require 'docker login'.
I struggled with this. I realized the image does not exist at https://hub.docker.com any more.
Just make sure to write the docker name correctly!
In my case, I wrote (notice the extra 'u'):
FROM ubunutu:16.04
The correct docker name is:
FROM ubuntu:16.04
The message usually comes when you put the wrong image name. Please check your image if it exists on the Docker repository with the correct tag.
It helped me.
docker run -d -p 80:80 --name ngnix ngnix:latest
Unable to find image 'ngnix:latest' locally
docker: Error response from daemon: pull access denied for ngnix, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'.
$ docker run -d -p 80:80 --name nginx nginx:latest
Unable to find image 'nginx:latest' locally
latest: Pulling from library/nginx
I had the same issue. In my case it was a private registry. So I had to create a secret as shown here
and then we have to add the image pull secret to the deployment.yaml file as shown below.
pods/private-reg-pod.yaml
apiVersion: v1
kind: Pod
metadata:
name: private-reg
spec:
containers:
- name: private-reg-container
image: <your-private-image>
imagePullSecrets:
- name: regcred
November 2020 and later
If this error is new, and pulling from Docker Hub worked in the past, note Docker Hub now introduced rate limiting in Nov 2020
You will frequently see messages like:
Warning: No authentication provided, using CircleCI credentials for pulls from Docker Hub.
From Circle CI and other similar tools that use Docker Hub. Or:
Error response from daemon: pull access denied for cimg/mongo, repository does not exist or may require 'docker login': denied: requested access to the resource is denied
You'll need to specify the credentials used to fetch the image:
For CircleCI users:
- image: circleci/mongo:4.4.2
# Needed to pull down Mongo images from Docker hub
# Get from https://hub.docker.com/
# Set up at https://app.circleci.com/pipelines/github/org/sapp
auth:
username: $DOCKERHUB_USERNAME
password: $DOCKERHUB_PASSWORD
I had the same issue
pull access denied for microsoft/mmsql-server-linux, repository does not exist or may require 'docker login': denied: requested access to the resource is denied
Turns out the DockerHub was moved to a different name
So I would suggest you re check-in docker hub
I solved this by inserting a language at the front of the docker image
FROM python:3.7-alpine
I had the same error message but for a totally different reason.
Being new to docker, I issued
docker run -it <crypticalId>
where <crypticalId> was the id of my newly created container.
But, the run command wants the id of an image, not a container.
To start a container, docker wants
docker start -i <crypticalId>
In my case I was using a custom image and docker baked into Minikube on my local machine.
I had specified the pull policy incorrectly:-
imagePullPolicy: Always
But it should have been:-
imagePullPolicy: IfNotPresent
Because the custom image was only present locally after I'd explicitly built it in the minikube docker environment.
I had this because I inadvertantly remove the AS tag from my first image:
ex:
FROM mcr.microsoft.com/windows/servercore:1607-KB4546850-amd64
...
.. etc ...
...
FROM mcr.microsoft.com/windows/servercore:1607-KB4546850-amd64
COPY --from=installer ["/dotnet", "/Program Files/dotnet"]
... etc ...
should have been:
FROM mcr.microsoft.com/windows/servercore:1607-KB4546850-amd64 AS installer
...
.. etc ...
...
FROM mcr.microsoft.com/windows/servercore:1607-KB4546850-amd64
COPY --from=installer ["/dotnet", "/Program Files/dotnet"]
... etc ...
I had the same issue when working with docker-composer. In my case it was an Amazon AWS ECR private registry. It seems to be a bug in docker-compose
https://github.com/docker/compose/issues/1622#issuecomment-162988389
After adding the full path "myrepo/myimage" to docker compose yaml
image: xxxxxxxxx.dkr.ecr.us-east-1.amazonaws.com/myrepo:myimage
it was all fine.
This error message might possibly indicate something else.
In my case I defined another Docker-Image elsewhere from which the current Docker inherited its settings (docker-compos.yml):
FROM my_own_image:latest
The error message I got:
qohelet$ docker-compose up
Building web
Step 1/22 : FROM my_own_image:latest
ERROR: Service 'web' failed to build: pull access denied for my_own_image, repository does not exist or may require 'docker login'
Due to a reinstall the previous Docker were gone and I couldn't build my docker using docker-compose up with this command:
sudo docker build -t my_own_image:latest -f MyOwnImage.Dockerfile .
In your specific case you might have defined your own php-docker.
If the repository is private you have to assign permissions to download it. You have two options, with the docker login command, or put in ~/.docker/docker.config the file generated once you login.
if you have over two stage in the docker build process read this solution:
this error message is completely misleading.
if you have a two-stage (context) dockerfile and want to copy some data from the first to the second stage, you must label the first context (ex: build) and access it by that label
#stage(1)
from <image> as build
.
.
#stage(2)
From <image>
copy --from=build /sourceDir /distinationDir
Docker might have lost the authentication data. So you'll have to reauthenticate with your registry provider. With AWS for example:
aws ecr get-login --region us-west-2 --no-include-email
And then copy and paste that resulting "docker login..." to authenticated docker.
Source: Amazon ECR Registeries
If you're downloading from somewhere else than your own registry or docker-hub, you might have to do a separate agreement of terms on their site, like the case with Oracle's docker registry. It allows you to do docker login fine, but pulling the container won't still work until you go to their site and agree on their terms.
Make sure the image exists in docker hub. To me, I was trying to pull MongoDB using the command docker run mongodb which is incorrect. In the docker hub, the image name is mongo.
If you don't have an image with that name locally, docker will try to pull it from docker hub, but there's no such image on docker hub.
Or simply try "docker login".
If you are using multiple Dockerfiles you should not forget to run build for all of it. That was my case.
I had to run docker pull first, then running docker-compose up again and then it worked.
docker pull index.docker.io/youruser/yourrepo:latest
Try this in your docker-compose.yml file
image: php:rc-zts-alpine
When I run the command multiple times "docker pull scrapinghub/splash" in Power shell then it solve the issue.
if it was caused with AWS EC2 and ECR, due to name issue(happens with beginners!)
Error response from daemon: pull access denied for my-app, repository does not exist or may require 'docker login': denied: requested access to the resource is denied
when using docker pull use Image URI of the image, available in ECR-row itself as Copy URI
docker pull Image_URI
I have seen this message and thought something was wrong about my Docker authentication. However, I've realized that Docker only allows 1 private repository per free plan. So it is quite possible that you are trying to pull your private repository and see this error because have not upgraded your plan.
Got the same problem but nothing worked. And then I understood I need run .sh (.ps1) script first before doing docker-compose.
So I have the following files:
docker-compose.yml
docker-build.sh
docker-build.ps1
Dockerfile
And I had to first run docker-build.sh on Unix (Mac) machine or docker-build.ps1 on Windows:
sh docker-build.sh
It will build an image in my case.
And only then after an image has been built I can run:
docker-compose up --build
For references. Here is my docker-compose file:
version: '3.8'
services:
api-service:
image: x86_64/prediction-service:0.8.1
container_name: api-service
expose:
- 8060
ports:
- "8060:80"
And here is docker-build.sh:
VERSION="0.8.1"
ARCH="x86_64"
APP="prediction-service"
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" >/dev/null 2>&1 && pwd )"
docker build -f $DIR/Dockerfile -t $ARCH/$APP:$VERSION .
I had misspelled nginx to nignx in Dockerfile
In my case the solution was to re-create docker-file through visual studio and all worked perfeclty.
I heard the same issue.
I solved by login
docker login -u your_user_name
then I was prompt to enter docker hub password
The rest command work perfect after login successfull
Someone might come across the same error for different reasons than what is already presented, so let me share:
I got the same error when using docker multistage builds (Multiple: FROM <> as <>).
And I forgot to remove one (COPY --from=<> <>)
After removing that COPY then it worked fine.
Exceeded Docker Hub's Limit on Free Repos:
Despite first executing:
docker login -u <dockerhub uname>
and "Login Succeeded" being returned, I received the error in this question.
In the webgui in Settings > Visibility Settings I remarked:
Using 2 of 1 private repositories.
Which told me that I had exceeded the limit on Docker Hub's free account limits. However, removing a previous image didn't clear the error...
The Fix:
Indeed, the error message in my case was a red herring- it's nothing related to authentication issues.
Deleting just the images exceeding the allowed limit did NOT clear the error however!
To get past the error you need to delete ALL the images in your FREE Docker Hub account, then run a new build pushing the image to your account.
Your pull command will now succeed.

Run a self-hosted agent in Docker

I am trying to run a self- hosted agent in docker, I have created the dockerfile and start.ps1 files and installed the Azure DevOps Server Express Admin console. I am getting a "Basic authentication requires a secure connection to the server " when I try running the container in docker ( switched windows containers) URL: http://computername/DefaultCollection
I have also attached a screenshot of the error
can you please advise how to resolve this issue.
Docker Run error
thanks
Run a self-hosted agent in Docker
I could not reproduce this issue on my side with hosted agent windows-2019.
To test this issue, I created a folder dockeragent in my Azure repo, which including the files Dockerfile and start.ps1:
Then copy the content from the document Run a self-hosted agent in Docker to those two files.
Next, create a pipeline with an inline powershell task to create the docker image and run docker container:
cd $(System.DefaultWorkingDirectory)\dockeragent
docker build -t dockeragent:latest .
docker run -e AZP_URL=https://dev.azure.com/<YourOrganizationName> -e AZP_TOKEN=<YourPAT> -e AZP_AGENT_NAME=mydockeragent dockeragent:latest
The test result:
To make it work, please make sure the file Dockerfile and start.ps1 is correct without any change.
If above info not help you, please share the content of your Dockerfile and the steps you did.
Your are using azureDevOps without https.
Registering your PiplineAgent via PAT requires https (hence the error: "Basic authentication requires a secure connection to the server".
Try using other authentication Methoden (negotiation, which uses windows authentication)

Docker-stack - get image always from the hub.docker.com

Summary: When I perform a 'docker stack deploy' in an AWS / EC2 environment the local (old) image is used. How can I overrule this behaviour to have the 'docker stack' use the new image from the hub.docker.com? As a workaround I first do a 'docker pull' of the image from index.docker.com before executing the 'docker stack deploy'. Is this extra step needed?
Situation:
On a Jenkins server (not on AWS / EC2) I have the following building steps:
Maven build
docker login -u ${env.DOCKER_USERNAME} -p ${env.DOCKER_PASSWORD}
docker build -t local-username/image-name:latest
docker tag local-username/image-name dockerhub-username/image-name:latest
docker push dockerhub-username/image-name:latest
The next steps in my Jenkinsfile are executed via a secure shell (ssh) on my AWS environement:
docker stack deploy -c docker-compose.yml stackname
When I execute this Jenkins job, the docker image is taken from the local image repo on AWS. I want to use the newest image put on hub.docker.com.
When I insert the following action BEFORE the 'docker stack deploy' everything works smoothly:
docker pull index.docker.io/dockerhub-username/image-name:latest
My questions:
Why do I need this extra 'docker pull' action?
How can I remove this action? Just by adding 'index.docker.io' in front of the image in the docker-compose.yml file? Or is there a better approach?
The extra docker pull should, of course not be needed.
What will help you?
The answer of #Tarun may work.
Or just name the Docker hub registry. Use the following line in your docker-compose.yml (stack) file
servicename:
image: index.docker.io/dockerhub-username/image-name
That will help you.
Maybe this is due to the fact that you build locally or on a separate Jenkins server, push the image to Docker hub and start on a remote shell on EC2. On that EC2 there is only a current image.
I tried the above solution for you, and it worked.
You can just execute the 'docker stack deploy' and the right image is used.

Not able to connect SpringBootApplication to mongo container in Docker

I'm having docker container up and running by using the following command:
docker run -p 27017:27017 -d mongo
Docker Logs for reference.
Then I clone a github repo: https://github.com/springframeworkguru/spring-boot-mongodb.git
Import the project in IntelliJ IDE, build it and run.
SpringBoot App Error Logs here
Issue : I'm not able to connect to the mongo app running in the container from my SpringBoot application as I'm getting MongoSocketOpenException as shown in the logs.
Any help is appreciated?
Docker version 18.03.0-ce, build 0520e24302
OS: Windows 10
Docker for win has some problems with loopback interfaces.
https://blog.sixeyed.com/published-ports-on-windows-containers-dont-do-loopback/
Try run docker inspect and configure your application with the container address.
Problem: I was trying to configure SpringBoot Application to mongo container IP which I retrieved from mongo inspect <mongo_container> command which was incorrect.
Solution: Configured my application using docker IP retrieved by docker-machine <env> which resolved the problem.
