img Not able to build simple docker file

Not able to build simple docker file

Open astrixj opened this issue 4 years ago • 9 comments

I've upgrade to the latest version v0.5.10 and there is a big regression as the following simple docker doesnt works

os: debian:buster

img build -t test .

FROM alpine:3.11

RUN apk update
RUN apk add vim
RUN apk add curl

This happen also with other docker files which works with version v0.5.7

This is the error

Setting up the rootfs... this may take a bit.

The img build for docker works, this issue was related to my complicated env , I was able to make it work. currently there are missing logs to understand where the problem is, using -d doesn't helps much

Could you explain what the issue was and how you fixed it? I'm still seeing this panic in my environment.

Regardless, the img tool should not panic. If there's a problem, there should be a nice error message explaining the problem as an output instead of a panic dump.

Sorry this related to our on-premise env hence I cannot share, I needed to make some tweaks to make it work. Did you try run it in a clean linux env ? if not could you try and share your feedback ? maybe I can assist, I agree about the panic this should be fixed in the upstream!

I tried running img on the real host - not inside any sort of container.

The first thing I tried was the binary that can be downloaded from the releases page. This binary crashed spectacularly on my host with the following panic:

$ /tmp/img-linux-amd64

I cloned the repository, and built my own img binary. This binary worked correctly and I was able it use it to build docker images. I then cleaned up the environment and rebuilt using the v0.5.10 tag - and that worked as well. I tried both "embedded runc" and "non-embedded run" variants - and as long as I build img myself - it runs correctly in my clean environment.

My guess is that there's some subtle difference in the build environments. The Golang version used by travis is 1.13.10 (as seen in the stack trace), while I'm using Golang 1.14.3. This is the most prominent difference - there may very well be more.

I believe #295 fixes this.

Jun 11 '20 07:06 fr33jc

EDIT: I was able to alleviate the error when building from source with the noembed build tag! This means @fr33jc 's PR #295 worked for me. Would love to have to have an official release tagged for this. :pray:

Getting the same issue here with version 0.5.10. I've tried in the following environments:

Ubuntu 20.04
Ubuntu 18.04 container
Ubuntu 20.04 container
Debian latest container

Building a simple Dockerfile. It'll run a few steps and then throw an error and exit. Here's the error I've generally been getting:

Same issue here, from what I've seen whenever a RUN instruction is present, also with v0.5.10. Can't use v0.5.7 since we export as tar's :) (which does not seem to be a feature in previous versions).

I think this can be closed since v0.5.11 has been released... works fine here.
