libpython2.7 was added to the container to allow running GDB built
with Python 2.7 support and distributed as part of the cross-compiler
toolchain.
Now that we have a new release of GDB which works with Python 3.x,
the GDB shipped with the cross-compiler is no longer used. Removing
libpython2.7 should reduce the image size.
This reverts commit be0372b1db.
Constraint files can be disabled with environment variable as well which
is useful when one uses the install/export scripts instead of
idf_tools.py directly. This is option is useful for offline build as
well.
Closes https://github.com/espressif/esp-idf/issues/9263
Replaces the previously used Docker Hub autobuild infrastructure.
This allows for more flexible configuration of the build process,
at the expense of some extra maintenance of CI workflow files
required.
These two arguments can be used to reduce the size of the Docker
image:
- Setting IDF_CLONE_SHALLOW enables shallow cloning.
- Setting IDF_INSTALL_TARGETS to the comma separated list of targets
results in toolchains being installed only for these targets.
