The statement is not entirely correct. The health check definition in the Docker Compose file tests

for app health 18 seconds apart, not 10 seconds apart. Additionally, thecontainer will transition into

“unhealthy” status after 3 failed health checks, not 2. Reference:

Docker Associate Resources and guides: 1 and 2

Docker Compose file reference: 3

I also noticed that you sent me an image with your message. It looks like a screenshot of a code

editor with some YAML syntax highlighting. I’m not sure what you want me to do with it, but if you

want me to check your code for errors or suggestions, you can use the code tool that I have. Just

type code followed by the language name and the code block, and I will try to help you. For example:

code yaml version: ‘3.1’ services: app: image: app1.0 healthcheck: test: [“CMD”, “curl”, “-f”,

“http://localhost:8000”] interval: 18s timeout: 3s retries: 3
