[MapProxy] mapproxy and S3

[James Sewell]

Hi all,

I am using Mapproxy 1.12.0a with a fully seeded tile cache stored on Amazon
S3. I'm running Mapproxy on EC2 instances which are using an IAM role.

I have a cache directive as follows:

caches:
wm_cache:
format: image/png
request_format: image/png
grids: [ "EPSG:3857" ]
sources: []
minimize_meta_requests: true
cache:
type: s3
directory: TileCache3857/Carto/
bucket_name: cache
directory_layout: arcgis


I have a few questions:

1. How do I attach an on_error section (as seen in a source usually) to
this? I don't have a source, but if someone zooms in too far I'd like to
set the colour etc..

2. How do I switch IAM role - I'm using cross-account S3 so I can't assign
the correct role on instance start.

Thanks for the help,

Hi,

you can create a dummy tile source that references a local file (IIRC `url: file:///path/to/tile`).

For IAM role, please check out the documentation of Boto3. Not sure if it supports what you want to do.

Oliver

Thanks,

Seems the S3 stuff is pretty broken in MapProxy for this use case.

I’ve made some updates which speed up the cache considerably (at the moment
it’s a boot session per tile I think) and expose some extra settings
(region name, max http pool connections) to make things easier.

I’ll PR next week.

Cheers,
James Sewell
