npm install step of the dockerfile seems to run each time, and takes a lot of time. even though package.json or lockfile remains unmodified.
I want to eventually move the dockerfile into a full dagger config soon. But just to get builds going first I'm using the Dockerfile still. Great that you added an dockerBuild() easy transitioning option 👏
Would you please also comment if I'm setting up dagger properly? I have several things that I'm not sure of. For example how to port .dockerignore files, how to utilize caching properly. should I mount the cache, where does the cache live, how does it get invalidated.
One gotcha was that even though Dockerfile has FROM --platform=linux/amd64 the dagger's result did not run on cloud run (which they require linux/amd64 and I'm building on an arm64 machine). Adding platform: 'linux/amd64' as Platform, to createBuild arg fixed it.
Here's part of my dagger script;
...
connect(
async daggerClient => {
const source = daggerClient
.host()
.directory(path.resolve(process.cwd(), '..'), {
exclude: [
'node_modules/',
'ci/',
'npm-debug.log',
'README.md',
'.next',
'.git',
'.env',
'gcp-dagger-service-account.json',
],
})
.dockerBuild({
platform: 'linux/amd64' as Platform,
dockerfile: 'apps/web/Dockerfile',
})
...
and the dockerfile
