Background information

The fix when 'No space left on device @ dir_s_mkdir - /opt/codedeploy-agent/deployment-root/..' occurs

• ssh to ssh -i ~/.ssh/synt-key-pair.pem [email protected]
• change :max_revisions: 1 in /etc/codedeploy-agent/conf/codedeployagent.yml
• clean up the folder sudo rm -rf /opt/codedeploy-agent/deployment-root/ca203350-bc6e-40a1-b01f-d4ca17fcdff7/*
• restart the service sudo service codedeploy-agent stop and then sudo service codedeploy-agent start

Start database with docker

• docker-compose -f docker-compose.yml up --build

• docker-compose up --build

Start production backend with docker

• docker build -t synt-backend .

• docker run -p 8000:8000 --network synt_backend_my-network synt-backend:latest

aws ecr --profile synt get-login-password --region eu-west-1 | docker login --username AWS --password-stdin 635199656487.dkr.ecr.eu-west-1.amazonaws.com
