Correct steps to building the container manually.

[dick-twocows]

I need to build the container manually due for various reasons but I do not seem to have the correct process...

Run docker build --tag toolchain ./ in the toolchain directory. Run docker build --tag xgo_1.20.4 ./ in the go-1.20.4 directory.

But the resulting image is different in size from the master so I'm assuming i'm missing something..? Also it fiails to build anything when passed in using the --image option...

xgo_1.20.4 latest a1671c0c6de3 About an hour ago 7.22GB techknowlogick/xgo latest 3bb43107e5b7 2 weeks ago 7.26GB

Run docker build --tag toolchain ./ in the toolchain directory. Run docker build --tag xgo_1.20.4 ./ in the go-1.20.4 directory.

Yeah, that's pretty much what I do to test changes locally, difference in size could be due to github actions using build or something.

With your last comment, it looks like the build at least started, did it complete?

[dick-twocows]

yes, but...

❯ ./xgo -v ~/oracle/engineering_and_support_tooling/hello-world-go/ works from the xgo directory

❯ ./xgo -v --targets=linux/arm64 ~/oracle/engineering_and_support_tooling/hello-world-go/ also works from the xgo directory

❯ ./xgo -v --targets=linux/arm64 --image=techknowlogick/xgo:latest ~/oracle/engineering_and_support_tooling/hello-world-go/ also works from the xgo directory and setting image

but the following fails... `❯ ./xgo -v --targets=linux/arm64 --image=xgo_1.20.4:latest ~/oracle/engineering_and_support_tooling/hello-world-go/ Checking docker installation...

it would appear to be missing something...

[dick-twocows]

success! thanks for you help :-)

I was missing the third step from docker/build.

❯ docker build --tag xgo:boom --file ./docker/build/Dockerfile ./

also needed to tag the second step to latest-base to match the FROM in the third step Dockerfile.

might be worth adding that to the README.md, do you want me to document the steps and open a PR?

i have a special case that I cannot pull from docker hub whilst inside the build pipeline but I can use images which are already pulled thus the requirement to actually docker build the image!

works setting the image ❯ ~/xgo/xgo -v --image xgo:boom ./ Checking docker installation... Client: ...

works from inside the docker container ` ❯ docker run -it -v ./:/hello-world-go --entrypoint /bin/bash xgo:boom root@e0d12fe4f798:/# cd /hello-world-go/ root@e0d12fe4f798:/hello-world-go# xgo -v --targets=linux/arm64 ./

ah fantastic. glad to hear it all worked out.
