This script will just run the above and then run our test in test_lamda.py. This step adds in our handler code (and any other files your Lambda might need) to the uber Layer and zips it up, ready for deployment.Įasy right? It’s a simple enough work-around, but it’s not immediately obvious! test-lambda.sh Building on the glowing reception of our Uberlayer Jacket, we ratcheted up the breathability while cutting the weight a little more to build the Ascendant CollectionPertex Microlight movement-mirroring stretch fabric and Polartec Alpha insulation create the perfect combination for skinning uphill, belaying, or layering under a ski jacket on cold days at the resort. ģ - Copy in Lambda code and zip up new uber Lambda: This step does what it says on the tin: we move everything up one directory so that we start to flatten the structure of the Layer into our uber Lambda. zip locally for our uses.Ģ - Unzip Layer and move all items up one directory: This removes unnecessary files that we don’t need in a Layer and zips up the dependencies into a proper Lambda Layer. We then run create-layer.sh which is also provided by RemotePixel. This block runs the RemotePixel Docker image remotepixel/amazonlinux:gdal3.0-p圓.7-cogeo which contains our required packages (rasterio, shapely etc.) installed via Python 3.7 and built against GDAL 3.0. ġ- Build Layer and extract zip of dependencies: Our uber Lambda might look like: $ ls unzipped-uber-layer/ handler.py package-1/ package-2/ binary1 binary2. This works because LocalStack is free doesn’t enforce the upload file size limits. In our version, we create an uber Lambda which contains all of the directory contents alongside the handler code! We can then deploy this as a Lambda, not a Lambda Layer. Inside it might look like: $ ls unzipped-layer/ python/ # Dir containing all your pip packages bin/ # Your packages may require binaries share/ # Ditto the above lib/ # Ditto also Normally, a Lambda Layer is a zip that would contain one or more directories but does not contain your handler code (as in the real world this is deployed separately). While it doesn’t mirror perfectly the normal Lambda Layer setup, you can still test your Lambdas with their dependencies. Currently we’re using the free version as we ❤️ Open Source and we also don’t like spending when we don’t need to!Īfter a week of experimenting and having a play, we found a way around this. If I lift my hands above my head the sleeves end up a little short, but I'm not climbing with it. One pain point I have with it though is that the free version does not support Lambda Layers, whereas LocalStack Pro does. Ascendant vs uberlayer plus Took it out today - 39F, 15MPH winds, 'feels like' 30F - with a SS poly plus lightweight Capilene LS underneath, plus a neck gaiter and a Polartec cap - and I was fine. I am asking sincerely, because I plan to buy either the Proton LT or the Ascendant hoody soon, and I want to make sure I correctly understand the pros and cons of each.Everyone who knows me knows that I ❤️ LocalStack. Do you have experience with Alpha not being durable? I’ve not noticed my fleece layers losing loft. First, how do you think the OR Ascendant hooded jacket would compare in this review?Īnd, you state that PolarTec Alpha insulation is not durable? Can you please explain why? I thought that since Alpha is basically long-pile fleece, it would not break or lose loft like short-fiber, loose synthetic insulation fills having very small fiber diameters. So Max, I have two questions if you would be kind enough to reply. And according to Max’s review, the Uberlayer is the same warmth as the Proton LT and Nano Air. The Ascendant uses the same weight of PolarTec Alpha insulation as the reviewed Uberlayer, so I assume they would both be the same warmth. The OR Ascendant hoody weighs a claimed 13.0 oz, which is a whole 1.4 oz lighter than the top-recommended Arcteryx Proton LT. And if you’re looking for a jacket that’s slightly heavier and a bit less breathable, Outdoor Research’s Uberlayer is also on sale and is even cheaper than the Ascendant.
