Warning due to no default checked-in toolchain configs for RBE Ubuntu 18.04

[cristifalcas]

I'm trying to use gcr.io/cloud-marketplace/google/rbe-ubuntu18-04 as the base image for a rbe container and I get this warning each time I run bazel:

rbe_default not using checked in configs; digest 'sha256:5703843282226b2f7db86afc0b1535f46d411fa72c1d540e1bd0f8064adb0bdb' was picked/selected but no compatible checked in config was found in map '{"sha256:06f8f8e9f97daa1c15466536dc2a7ae6641d16962d7b58a393af8060e460f571": ["10.0.0"], "sha256:09fbb5438d51626dabfe096db381b733af6ed5fd59f07f0a311840598f78019c": ["9.0.0"], "sha256:1ab40405810effefa0b2f45824d6d608634ccddbf06366760c341ef6fbead011": ["10.0.0"], "sha256:1e7bf60f191f6221b010f9338b57936d378baa7b6488dcf5235e2939d62fb9ec": ["10.0.0"], "sha256:29dc13bace3faca2b42e8dbd32c314bed960c313b9e144575eee58338eead9a8": ["10.0.0"], "sha256:2b73cbf679cbf11ed1f782511d3eb8ec7d69049b5947f503c190e9352fd27289": ["9.0.0"], "sha256:2c925275fb30478602cd53651eeaaf015f964ad1b84d3947ed710802f054035b": ["9.0.0"], "sha256:3c104745837918f854415f78f63afe7f680f0876dda837058c38e6eee54e253c": ["10.0.0"], "sha256:3e98e2e1233de1aed4ed7d7e05450a3f75b8c8d6f6bf53f1b390b5131c790f6f": ["9.0.0"], "sha256:4bfd33aa9ce73e28718385b8c01608a79bc6546906f01cf9329311cace1766a1": ["10.0.0"], "sha256:57fbf17cb0d43fb7a00b4e0476750643cb80377e5c38b2e28490d6c69ad8fa2d": ["10.0.0"], "sha256:677c1317f14c6fd5eba2fd8ec645bfdc5119f64b3e5e944e13c89e0525cc8ad1": ["9.0.0"], "sha256:69c9f1652941d64a46f6f7358a44c1718f25caa5cb1ced4a58ccc5281cd183b5": ["9.0.0"], "sha256:6ad1d0883742bfd30eba81e292c135b95067a6706f3587498374a083b7073cb9": ["10.0.0"], "sha256:823aa3cc811b40d8cd7a8df529553ceb8a49bf2adffcebedc4e49dbd8daafca0": ["9.0.0"], "sha256:87d0fa2c56558f2f0d05116e6142b29d9ee509776be5fa9794a57f281b75b14e": ["10.0.0"], "sha256:87e1bb4a47ade8ad4db467a2339bd0081fcf485ec02bcfc3b30309280b38d14b": ["10.0.0"], "sha256:87fe00c5c4d0e64ab3830f743e686716f49569dadb49f1b1b09966c1b36e153c": ["8.0.0"], "sha256:91739a2a3979753111d563fc0202e10e9cd8b9b2ce9552d6a7213892cfe2deb7": ["10.0.0"], "sha256:93f7e127196b9b653d39830c50f8b05d49ef6fd8739a9b5b8ab16e1df5399e50": ["10.0.0"], "sha256:94d7d8552902d228c32c8c148cc13f0effc2b4837757a6e95b73fdc5c5e4b07b": ["9.0.0"], "sha256:98cd34f400a696c0409a3aa0411923b7198aced800a84f23b31f883f8bf407e7": ["9.0.0"], "sha256:9bd8ba020af33edb5f11eff0af2f63b3bcb168cd6566d7b27c6685e717787928": ["8.0.0"], "sha256:9d3104c820537dbf975c78048ddbe71d3f82515cf92b1106ddc552292c187511": ["10.0.0"], "sha256:ac36d37616b044ee77813fc7cd36607a6dc43c65357f3e2ca39f3ad723e426f6": ["10.0.0"], "sha256:aec4629f0856fef325ad03e6b593ccc52eff3328ced6cac351667b85eec48f88": ["9.0.0"], "sha256:bc6a2ad47b24d01a73da315dd288a560037c51a95cc77abb837b26fef1408798": ["9.0.0"], "sha256:d4edc52e8c0171905fc43773846b84d8d6ab4f75354986b82f9eddb6563bbe0f": ["10.0.0"], "sha256:d7bea5c70932edfddafda2da51814a17712585df319bbc11b4d17f662aec6c46": ["9.0.0"], "sha256:da0f21c71abce3bbb92c3a0c44c3737f007a82b60f8bd2930abc55fe64fc2729": ["9.0.0"], "sha256:ec8710e636220c090b84f80a657a61b548dc94d4e3df5e3c42ca048ca74bcfb0": ["10.0.0"], "sha256:f3120a030a19d67626ababdac79cc787e699a1aa924081431285118f87e7b375": ["8.0.0"], "sha256:f5d13baa00009baffb87194cd52cef0165b52d37477093ff72410114664f4380": ["9.0.0"], "sha256:f6fb11fbdc2965f7fef1bcc81565e5bc41a6a91d5ee7a375dbb3a8ea130de5f1": ["9.0.0"], "sha256:fbd499b53a377fe2c6c5e65c33bdecd9393871e19a64eaf785fb6491f31849d3": ["9.0.0"], "sha256:fd5690d000da5759121f28ccbc19ebb4545841d816bbf6a72de482cf3e7ce491": ["10.0.0"]}'

What does it involve to add support for 18.04?

This is expected because we don't automatically generate and publish toolchain configs for the RBE Ubuntu 18.04 container here.

An alternative is to generate and host configs in your own repository using the toolchain_config_suite_spec attribute There's some documentation elsewhere in the file I linked on how to use this attribute to host your own configs. Also see here for an example.

Another option is to add an attribute to the rbe_autoconfig macro to suppress the warnings if you're okay with it generating the configs on the fly and don't want to see the warning.

Any plans to support a more up to date ubuntu?
