dockbuild / dockbuild Goto Github PK

@thewtex @jcfr do you have this set up somewhere already? I could not find them under docker hub dockcross.

Makefile should allow to build and push

Example: https://github.com/jcfr/dockgit-rocket-filter/blob/master/Makefile

Currently dockbuild/centos6:latest includes devtoolset-2 but some project can also require devtoolset-3, what should be the name of our dockbuild images;

dockbuild/centos6:latest                          # default is devtoolset2
dockbuild/centos6devtoolset3:latest

or consistently rename all images as such (my preferred approach):

dockbuild/devtoolset2-centos5:latest
dockbuild/devtoolset2-centos6:latest                  
dockbuild/devtoolset3-centos6:latest
dockbuild/devtoolset4-centos7:latest

dockbuild/gcc44-ubuntu1004:latest
dockbuild/gcc54-ubuntu1604:latest
dockbuild/gcc73-ubuntu1804:latest

If you run python -c 'import bz2' you'll get the error

Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named bz2

This is because bzip2-devel isn't installed when python is built. This can be fixed by adding
yum install bzip2-devel
to the Dockerfile before python is configured/built.

This might seem like an obscure thing, but not having bz2 can screw up pip's ability to download the latest version of a package. You'll see unsupported archive format: .tar.bz2 if you run pip install -v <package>.

Tried this with the centos5 image:

$  docker run --rm dockbuild/centos5-devtoolset2-gcc4 

but nada

For the record, @jcfr wrote this

I added includes folder to work dir (C++), it is requested like this
#include <includes/file.h> in many files
I added include_directories("/work/includes") in CMakeLists.txt
But compilation terminated. fatal error: includes/file.h: No such file or directory

How to add include folders?
Thanks!

build from source + add symlink from /root/... to '/usr/local/...'

Running the default example there seems to be no conan utility installed. Running pip install conan as a prerequisite won't work directly because the install destination isn't writable, using pip install --user conan seems to install it in a black hole that can't be found (it's not put in ~/.local/bin).

I'm finding the same problem on dockcross so came here for a simpler setup to investigate. Any ideas?

I depend on boost to build, what is the most idiomatic way here? I can see conan, apt/yum, or building the source in the mounted directory as options.

See https://github.com/dockcross/dockcross/blob/master/.github/workflows/main.yml

I suggest

(1) we adopt the following tagging convention for docker image:

• centosX-latest
• centosX-YYYYMMDD

(2) tag source repository using tag like these ones:

• centosX-YYYYMMDD

I also suggest we rename (or copy) the existing tag v1.0.0 to centos5-20151210

(2) we option to manage the sources of the different images:

(a) create maintenance branch for each version of centos we support: centos5, centos6 and centos7

and also a branch named welcome with a README.md explaining what is available in this repo.

(b) add subdirectory like centos5, centos6, centos7 .... Since dockerhub support specifying location of dockerfile, this should work well too: https://docs.docker.com/docker-hub/builds/#create-an-automated-build

Python is currently built as a static executable, but it seems the usual way of building it is with --enable-shared (it's that way on Ubuntu, etc). Having a python .so allows for other uses of python than just running the interpreter.

For comparison, it looks like Docker's own official python builds do this:
https://github.com/docker-library/python/blob/master/Dockerfile-debian.template#L41

This is causing issue with build SlicerDocker

$ docker run -ti thewtex/centos-build:v1.0.0 bash

xref #33 (comment)

Compilers installed. tools in the path, version of GLIBC/GLIBCXX, etc .. should all be documented. A place for that could either be the wiki or README along side the Dockerfile.

 $ docker run dockbuild/ubuntu1004

I'm assuming this should be updated to > dockbuild-ubuntu1004

Instead of maintainer the image on thewtex, what do you think of creating a GitHub organization named dockbuild (similar to the existing dockcross one) ?

Similarly to dockcross, we should have tagged images with the following name YYYYMMDD-SHA{7}
