Will Windows Containers Be Cached, or Downloaded Each Time?


#1

Windows containers are likely to be larger than 10 GB very often (due to MS Build Tools). It seems likely that Travis will have some mechansim to cache these images so that they don’t have to download them from scratch every time. It also seems likely that Travis has already been caching like this for Linux builds as well, but because they’re far smaller on average, we never thought to ask.

If the answer is yes, does this apply to only the base os layers, or would it also cache user-created layers?
