# This .bazelrc file contains all of the flags required for the toolchain,
# Remote Build Execution, and the Bazel Build Results UI. Specific flags in
# your Bazel command allow you to use only the remote build, to use only the
# results UI, or to use them both together.
#
# This .bazelrc file also contains all of the flags required for the local
# docker sandboxing.

# Remote Build Execution requires a strong hash function, such as SHA256.
startup --host_jvm_args=-Dbazel.DigestFunction=SHA256

# Depending on how many machines are in the remote execution instance, setting
# this higher can make builds faster by allowing more jobs to run in parallel.
# Setting it too high can result in jobs that timeout, however, while waiting
# for a remote machine to execute them.
build:remote --jobs=50

# Set several flags related to specifying the platform, toolchain and java
# properties.
# These flags are duplicated rather than imported from (for example)
# %workspace%/configs/ubuntu16_04_clang/1.0/toolchain.bazelrc to make this
# bazelrc a standalone file that can be copied more easily.
# These flags should only be used as is for the rbe-ubuntu16-04 container
# and need to be adapted to work with other toolchain containers.

# The toolchain container used for execution is defined in the target indicated
# by "extra_execution_platforms", "host_platform" and "platforms".
# If you are using your own toolchain container, you need to create a platform
# target with "constraint_values" that allow for the toolchain specified with
# "extra_toolchains" to be selected (given constraints defined in
# "exec_compatible_with").
# More about platforms: https://docs.bazel.build/versions/master/platforms.html
