Increased (+50%) docker image size with v18.9.1 (from v16.16.0)

[patoi]

Environment

• Platform: Ubuntu Linux 22.4
• Docker Version: Docker version 20.10.18, build b40c2f6
• Node.js Version: v18.9.1
• Image Tag: 18.9.1-alpine3.16

Expected Behavior

The v16.16.0-alpine3.16 size is 112MB, I expected that v18 image size is nearly same amount of MB.

node 16.16.0-alpine3.16 b1ca7421d2e7 6 weeks ago 112MB

Current Behavior

The v18.9.1-alpine3.16 image size is 167MB.

node 18.9.1-alpine3.16 f4e0e36b202c 19 hours ago 167MB

Possible Solution

Steps to Reproduce

Additional Information

The /usr/local/include/node/openssl folder is now 50MB instead of 3MB. Is anyone familiar with that folder and could investigate why there is such a huge increase?

@nodejs/build is this known?

Build group does not support Alpine, it is fully unofficial support

@nschonni

This affects non-alpine images as well. Just download Node.js 18 tar from node official site and untar it. You will notice that the include directory is 50 MB.

The /include/node/openssl/archs contains all distribution headers, I think it's unnecessary.

@nodejs/build is this known?

Yes, nodejs/node#42081.

[SimenB]

Since that issue is closed, should we close this? The fix for it was included in nodejs/node#42943 from what I can tell. Or should we tweak something in our dockerfiles?

[patoi]

I think it can be closed because nodejs/node#45454 has opened.
