Are you a lazy programmer?

Yeah, not deploying on a Friday has nothing to do with a lack of CI; it’s related to the human culture of having a weekend, which reduces an organisation’s ability to handle the unforeseen consequences of pushing to production.

“So just roll back” I hear you say, to which I respond: “it ain’t always that easy”. You can’t always just turn the reactor off once the meltdown is in progress.

We've had this issue many times with dependency management.

CI will rebuild after you revert everything and still fail to deploy if you pushed a versioned library from your broken code.

Go into your environment and manually roll back to a working image... and learn a powerful lesson.

I'm not sure what you're saying here. I can see this being a problem when you have cross-team dependencies and your roll-back requires coordination.

Even then it's manageable if your production deployments are version pinned, it only becomes a problem if schemas in your database or messaging have had non compatible changes and data has been written (i.e you have binary and data dependencies in a release)

All this being said with the assumption that the CI/CD pipeline has been designed to best practices.
