This reduces the container size from 1.4 GB to 640 MB. 129 MB is
jessie, 489 MB jdk, and 22 MB grpc-java. When we swap from jessie to
stretch, we could swap to openjdk:8-jdk-slim-stretch which would make
the entire image 265 MB.
Python was never needed; it was added by mistake in 0589e533.
Pre-downloading gradle artifacts isn't helpful these days, because we
build on a clean machine. Git isn't needed as cp is sufficient. libapr1
has not been required by tcnative for a long time, and we even use
tcnative-boringssl-static since at least 1.0, which also doesn't need
it. The final cleanup is to remove source and downloaded artifacts when
done compiling.
Jessie has a line that looks like this, now-a-days, so the regex is no
longer matching:
deb http://security.debian.org/debian-security jessie/updates main
But because that line was changed, downloads are also working correctly
out-of-the-box. The sed was originally added in #18530.
six is necessary for making these scripts cross compatible
between python 2.x and 3.x
Changes:
Add six to python_deps.include
Include python_deps.include to all Dockerfile templates in test directory
Include python_deps.include to all Dockerfile templates in stress_test directory
Include python_deps.include to all Dockerfile templates in interop_test directory
Replace print statements with print function calls (from futute..)
Replace .iteritems() with .items() wherever necessary
use six.moves to import BaseHTTPServer
Generate new dockerfiles using generate_projects.sh
We commit the codegen into Git, so it is already available. Travis-CI is
testing the codegen, so we don't need to test it as part of interop
tests.
This means we no longer need a C compiler installed, so we stop using
grpc/base.
The images seem to have been broken starting with 12e12a3, but the
removal of Maven support from grpc-java also broke them further.
SSH handling no longer uses $HOME as it does not agree with /etc/passwd
in older docker versions[1] and prevented SSH from seeing the config
file.
Some effort was also made to reduce the image sizes by removing
temporary files.
