We have set the CI/CD pipeline in amplify and since 22nd Dec the backend build is getting failed and throwing the error "Failed to pull the backend" as per the attached screenshot,
Expected behavior: The build should be successfully completed. Here I'm attaching the last successful build screenshot,
I tried to redeploy the last successful build, but that also failed and gave the same error.
version details,
Node.js: 16.18.1
Amplify CLI Version: 10.5.2
OS: Amazon Linux 2
NOTE: The project is working fine locally, and also the amplify pull command runs successfully. In local I'm using windows.
Thank you.
I am trying to deploy a django app to elastic beanstalk. This worked well initially but I have recently made a change to the database models and so need to migrate these in the production environment.
Looking at old logs I can see there was not a problem with this previously, but now the migrate command is not found:
2022/05/23 07:45:34.726621 [INFO] Executing instruction: RunAppDeployPostDeployHooks
2022/05/23 07:45:34.726634 [INFO] Executing platform hooks in .platform/hooks/postdeploy/
2022/05/23 07:45:34.726654 [INFO] The dir .platform/hooks/postdeploy/ does not exist
I am deploying using eb deploy and I the path mywebsite/.platfrom/hooks/postdeploy/01_migrate.sh exists. Does anyone know why it is not being found?
Use
/var/app/current/.platform/hooks/postdeploy
I am getting the below error in my GCP Cloud Run service:
Error: Could not find or load main class com.sdas.demo.sd.Application
Caused by: java.lang.ClassNotFoundException: com.sdas.demo.sd.Application
What I was doing:
I have a spring boot application where I used jib-maven-plugin. In BitBucket pipeline, I was executing the below command:
mvn clean compile com.google.cloud.tools:jib-maven-plugin:3.1.4:build -Dimage=eu.gcr.io/sdas-demo-dev/temp-service
After that deploying this GCR image to Cloud Run using gcloud command from BitBucket pipeline. This deployment failed with the error that 'Could not load main class'.
But if I run the mvn clean compile com.google.cloud.tools:jib-maven-plugin:3.1.4:build -Dimage=eu.gcr.io/sdas-demo-dev/temp-service from my computer git bash for the same spring boot application code and then deploy it to Cloud Run (via gcloud command or via console or via pipeline); it's deployed successfully.
I used 'mainClass' tag under jib-maven-plugin in pom.xml. But still it is unable to find or load the main class.
Can anyone help how to identify the problem? Is this a classpath issue or environment issue?
Issue sorted now.
Root cause:
'No resources found to compile' - I found this message in the build log. This message remind me something wrong within the application package.
My system is running on Windows 10 and my application directory starting with 'Java.com.demo.sdas' (J in capital). Since Windows is case in sensitive; it is not causing an issue.
BitBucket pipeline running on Linux server and it is case sensitive. Thus it is unable to find the application directory starting with 'Java.com.demo.sdas'.
Solution: Renamed the directory as 'java' and then everything is working as expected.
I would like to deploy a JAVA application (based on PlayFramework 1.x) on AWS Beanstalk.
I am using a web server environment based on Corretto 8 running on 64bit Amazon Linux 2/3.1.6.
I also added a load balancer in the environment.
During the deployment, my hooks work well (database schema evolutions for example) then comes the time to launch the web server.
The deployment fails with the following error:
[ERROR] update processes [web cfn-hup nginx healthd] pid symlinks failed with error Read pid source file /var/pids/web.pid failed with error:open /var/pids/web.pid: no such file or directory
[ERROR] An error occurred during execution of command [app-deploy] - [Track pids in healthd]. Stop running the command. Error: update processes [web cfn-hup nginx healthd] pid symlinks failed with error Read pid source file /var/pids/web.pid failed with error:open /var/pids/web.pid: no such file or directory
I don't use any specific configuration for nginx.
I run the JAVA application on the default port (5000).
I saw on the AWS forums and stackoverflow that some people had this problem on worker environments but I don't use this configuration.
Have you ever encountered this problem?
Your web.service is not able to start. You might be missing a manifest in your jar, or you might be missing the main class in your manifest file.
I'm deploying a docker image from Github to AWS elastic beanstalk using travis. That part goes OK, the actual deployment exits with 0 and there is a .zip file in the S3 bucket.
The issue is that, since this is my first time using AWS I created the app using the Sample Application since the code is deployed from Github, and after the deployment I get the health status as degraded (red exclamation sign) with this message:
ERROR
During an aborted deployment, some instances may have deployed the new application version. To ensure all instances are running the same version, re-deploy the appropriate application version.
If I go to Causes I find this:
Application deployment failed at 2020-05-01T16:01:58Z with exit status 1 and error: Engine execution has encountered an error.
Incorrect application version "travis-e55e05342a8cc16f3f28f8e184735667a9531ffa-1588311901" (deployment 4). Expected version "Sample Application" (deployment 1).
I even deleted the sample application and re-deployed the one that was uploaded and got that particular error. As you can see in the last message I've deployed this 3 times already, getting the same result.
Finally I downloaded the zip file from the S3 bucket and I found inside basically the src and public folders along with all the files in the root folder such as package.json, .gitignore all the docker files, etc.
EDIT
I created two separate repos in github to test this.
The first repo is a static page in a Docker container, quite simple. I create an environment in EB and start everything with the sample app. Then I push the changes to github, travis does it's thing and deploys the app to AWS. This works fine and the app's env is updated with no errors. This is the repo:
https://github.com/rhernandog/docler-static-page-aws
The second repo is a simple react app. Same procedure, create the environment in EB with the sample app. Push the code to github, travis does it's thing and deploys to AWS. This fails and I keep getting the same error:
Environment health has transitioned from Info to Degraded. Command failed on all
instances. Incorrect application version found on all instances. Expected version
"Sample Application" (deployment 1). Application update failed 1 second ago and
took 2 minutes.
This is the repo for the react app:
https://github.com/rhernandog/react-docker-awseb
In terms of Docker, everything works fine in my local machine.
EDIT 2
Based on #stefansundin suggestion I re-deployed the app to EB and check the logs. I ended looking at the full logs for more information and found this:
/var/log/cfn-hup.log
2020-05-14 17:07:42,605 [WARNING] Action for aws-eb-command-handler exited with 1, returning FAILURE
The only place where I found an error was in the engine log file:
/var/log/eb-engine.log
2020/05/14 17:07:42.514601 [INFO] Executing instruction: Docker Specific Build Application
2020/05/14 17:07:42.514605 [INFO] start build docker app

2020/05/14 17:07:42.558923 [ERROR] "docker pull" requires exactly 1 argument.
So basically this is complaining about this in the dockerfile: FROM node:12-alpine AS builder. You can see the whole file in the repo: https://github.com/rhernandog/react-docker-awseb/blob/master/Dockerfile
The point is: Why this doesn't happen in my local machine? And how can I actually get the files from the build command and copy them to the nginx folder?
That is actually the only error I found in the log files.
I solved the issue here:
AWS Elastic Beanstalk Docker Does not support Multi-Stage Build
it is a stage-naming problem of multi-stage Dockerfile. Just use an Unamed one
I also got a similar error in my node app:
Incorrect application version "travis-e55e05342a8cc16f3f28f8e184735667a9531ffa-1588311901" (deployment 4). Expected version "Sample Application" (deployment 1)
What turned out to be an issue with my building and deployment scripts were corrected (debugged in Jenkins) the application successfully deploys in beanstalk with no error.
Turns out the issue was not with Beanstalk or app version but with the build mechanism. Something to look into when nothing else works :)
I had the same issue for java app in docker container.
I tried all the recommendations from this topic, links from this topic and nothing helped.
In the end, the following action helped:
Enable enhanced health panel https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/health-enhanced-enable.html#health-enhanced-enable-console
Go to the extended panel of the desired environment
Select the instance that crashed due to this "version" issue and click reboot
Additionally:
In one of the cases, I had to delete all previous versions (section on the left panel) and push a new one and only after that make the above recommendations.
Also make sure you have sufficient rights to deploy (codepipeline/deployment)
AWS Docs say that
To solve this issue, start another deployment. You can redeploy a previous version that you know works, or configure your environment to ignore health checks during deployment and redeploy the new version to force the deployment to complete.
You can also identify and terminate the instances that are running the wrong application version. Elastic Beanstalk will launch instances with the correct version to replace any instances that you terminate. Use the EB CLI health command to identify instances that are running the wrong application version.
Can you try to delete the instances that runs your applications and start a fresh install?
Also, you can use CodePipeline to deploy your codes to Elastic Beanstalk, you can use your S3 folder for the source stage and skip the build process if your code is build on travis and deploy using the deploy stage to install your new app to your Elastic Beanstalk. There might be some misconfiguration while installing the new app to your environment.
I suggest you to terminate your instances and start new instances sorry if I got your question wrong.
I haven't used Docker on Elastic Beanstalk. When my Ruby on Elastic Beanstalk deployments fail, I find that I usually find the problem if I request the 100 last lines from the logs. If you navigate to "Logs" -> "Request Logs" -> "Last 100 Lines", that may help you.
If that fails, I SSH in to the instance and look in the logs in /var/log. Maybe docker ps and docker logs may help you.
While creating a new webserver environment on platform branch select "Docker running on 64bit Amazon Linux" it will work.
