I am building a large Bazel project in a cloud VM with /tmp in a small filesystem (~8 GB). Occasionally my build fails with the error Not all outputs were created: the filesystem containing /tmp is at 99% of capacity, and /tmp contains many Bazel build artifacts.
How can I override the temporary directory that Bazel uses? I tried setting the TEMP and TMPDIR environment variables when starting bazel build, but this did not help.
If you are using the configure_make rule from rules_foreign_cc, unfortunately you have no way to influence where the built deps are stored.
See https://github.com/bazelbuild/rules_foreign_cc/blob/master/cc_configure_make/def.bzl#L44
"tmpdir=$(mktemp -d)",
"tmpinstalldir=$(mktemp -d)",
I think you want the --test_tmpdir=<a_path> command line argument to the bazel command.
--test_tmpdir=<a path> default: see description
Specifies the base temporary directory for 'bazel test' to use.
