bazel-remote

A remote cache for Bazel using HTTP/1.1.

The cache contents are stored in a directory on disk. One can specify a maximum cache size and bazel-remote will automatically enforce this limit and clean the cache by deleting files based on their last access time. The cache requires Bazel to use SHA256 as its hash function.

Using bazel-remote

Usage of bazel-remote:
  -dir string
    	Directory path where to store the cache contents
  -max_size int
    	The maximum size of the remote cache in GiB (default -1)
  -port int
    	The port the HTTP server listens on (default 8080)

Configuring Bazel

In order to set up Bazel for remote caching, it needs to be passed some special flags.

bazel 
  --host_jvm_args=-Dbazel.DigestFunction=sha256 
build
  --spawn_strategy=remote
  --strategy=Javac=remote
  --genrule_strategy=remote
  --remote_rest_cache=http://<BAZEL-REMOTE-HOST>:<PORT>
//foo:target

Specifying these flags on each Bazel invocation can be cumbersome and thus one can also add them to their ~/.bazelrc file

startup --host_jvm_args=-Dbazel.DigestFunction=sha256
build --spawn_strategy=remote
build --strategy=Javac=remote
build --genrule_strategy=remote
build --remote_rest_cache=http://<BAZEL-REMOTE-HOST>:<PORT>
