// you are using a pack builder that doesnt work on arm64

docker exec -it dokku bash dokku buildpacks:set nextjs-blank-dokku https://github.com/heroku/heroku-buildpack-nodejs.git



docker exec -it dokku bash dokku buildpacks:report

Buildpacks computed stack:     gliderlabs/herokuish:latest-20



```



```bash

docker exec -it dokku bash dokku buildpacks:remove nextjs-blank-dokku https://github.com/heroku/heroku-buildpack-nodejs.git



https://dev.to/emdienn/deploy-sveltekit-on-dokku-in-8-sort-of-easy-steps-28g2



docker exec -it dokku bash dokku buildpacks:set-property --global stack paketobuildpacks/builder:base



docker exec -it dokku bash dokku buildpacks:set-property --global stack heroku/builder:22



# unset globally

https://dokku.com/docs~v0.25.7/deployment/builders/herokuish-buildpacks/#removing-a-buildpack



# set globally

dokku buildpacks:set-property --global stack gliderlabs/herokuish:latest



# unset globally

docker exec -it dokku bash dokku buildpacks:set-property --global stack

```



### Solution



```ts

// can use main, no need for master

git push dokku main:main



// can use default

gliderlabs/herokuish:latest



// solves all arm64 dependencies, postgres, node.js...

https://github.com/tonistiigi/binfmt

https://hub.docker.com/r/tonistiigi/binfmt



// this line, container installs and configures the host

docker run --privileged --rm tonistiigi/binfmt --install all



// todo:

routing and https fails, add dokku config



```



### Fix routing



docker exec -it dokku bash dokku domains:report --global



docker exec -it dokku bash dokku domains:report nextjs-blank-dokku



docker exec -it dokku bash dokku proxy:ports nextjs-blank-dokku



### Check if app container is running, not only Dokku container - Process Management



docker exec -it dokku bash dokku ps:start nextjs-blank-dokku



#### Rebuild



docker exec -it dokku bash dokku ps:rebuild nextjs-blank-dokku



### Lets encrypt https



this is plugin, not dokku config



https://github.com/dokku/dokku-letsencrypt



docker exec -it dokku bash dokku plugin:install https://github.com/dokku/dokku-letsencrypt.git

docker exec -it dokku bash dokku config:set --no-restart nextjs-blank-dokku DOKKU_LETSENCRYPT_EMAIL=acczasearchapi@gmail.com



docker exec -it dokku bash dokku letsencrypt:set nextjs-blank-dokku acczasearchapi@gmail.com



docker exec -it dokku bash dokku letsencrypt:enable nextjs-blank-dokku acczasearchapi@gmail.com

# After solved network error



### Add remote, create app and push



```bash

git remote add dokku dokku@dokku.arm1.localhost3002.live:nextjs-app



dokku apps:create nextjs-app



dokku apps:list



# check if added

dokku network:report node-app



git push dokku main:main

```



Traefik wont request cert for http app route



```bash

ubuntu@arm1:~/traefik-proxy/core$ curl https://node-app.dokku.arm1.localhost3002.live/

curl: (35) error:0A000126:SSL routines::unexpected eof while reading

```



Traefik has passthrough, Dokku must handle ssl



```

Error while dialing backend: dial tcp 172.21.0.4:443: connect: connection refused"

```



curl http://nextjs-app.dokku.arm1.localhost3002.live

curl https://nextjs-app.dokku.arm1.localhost3002.live



### Solve let Dokku http through Traefik https



https://dokku.com/docs/networking/proxies/nginx/#hsts-header



```bash

username@computer3:~/Desktop/dokku-nextjs-hello-world$ curl https://nextjs-app.dokku.arm1.localhost3002.live

curl: (35) error:0A000126:SSL routines::unexpected eof while reading



dokku nginx:set --global hsts false



dokku ps:stop nextjs-blank-dokku

dokku ps:start nextjs-blank-dokku

```



### Lets encrypt



https://github.com/dokku/dokku-letsencrypt



dokku letsencrypt:set --global email your@email.tld



dokku letsencrypt:enable nextjs-app
