minio single node single disk docker compose with letsencrypt tls

How to have a single node minio instance,
with docker compose,
and auto updating letencrypt certificate.

Prerequisite:
A way to obtain a cert for your domain via certbot.
The certs should already exist and be able to be renewed.

1st create the docker minio directories.

mkdir -p /docker/minio/data
mkdir -p /docker/minio/certs

1 2	mkdir -p /docker/minio/data mkdir -p /docker/minio/certs

/docker/minio/compose.yaml

name: minio
services:
    minio:
        ports:
            - 9000:9000
            - 9001:9001
        container_name: minio
        volumes:
            - /docker/minio/data:/data
            - /docker/minio/certs:/root/.minio/certs
        environment:
            - MINIO_ROOT_USER=rootuser
            - MINIO_ROOT_PASSWORD=rootpassword
        image: quay.io/minio/minio
        command: server /data --console-address ":9001"

name: minio

services:

minio:

ports:

- 9000:9000

- 9001:9001

container_name: minio

volumes:

- /docker/minio/data:/data

- /docker/minio/certs:/root/.minio/certs

environment:

- MINIO_ROOT_USER=rootuser

- MINIO_ROOT_PASSWORD=rootpassword

image: quay.io/minio/minio

command: server /data --console-address ":9001"

/etc/letsencrypt/renewal-hooks/deploy/copy-certs.sh

#!/bin/bash

TARGET_HOME=/docker/minio
TARGET_DOMAIN=domain.tld

if [[ $RENEWED_DOMAINS == *" $TARGET_DOMAIN "* ]]; then
        cp -L /etc/letsencrypt/live/$TARGET_DOMAIN/* $TARGET_HOME/certs/
	cd $TARGET_HOME
	docker compose up -d
fi

#!/bin/bash

TARGET_HOME=/docker/minio

TARGET_DOMAIN=domain.tld

if [[ $RENEWED_DOMAINS == *" $TARGET_DOMAIN "* ]]; then

cp -L /etc/letsencrypt/live/$TARGET_DOMAIN/* $TARGET_HOME/certs/

cd $TARGET_HOME

docker compose up -d

And finally start it

chmod +x /etc/letsencrypt/renewal-hooks/deploy/copy-certs.sh
cd /docker/minio/certs
cp -L /etc/letsencrypt/live/domain.tld/* /docker/minio/certs/
ln -s fullchain.pem public.crt
ln -s privkey.pem private.key
cd ..
docker compose up -d

chmod +x /etc/letsencrypt/renewal-hooks/deploy/copy-certs.sh

cd /docker/minio/certs

cp -L /etc/letsencrypt/live/domain.tld/* /docker/minio/certs/

ln -s fullchain.pem public.crt

ln -s privkey.pem private.key

cd ..

docker compose up -d

How to package your SPA or PWA without a Dockerfile using Go and ko

Writing Dockerfiles is a pain in the ass.
All you want to do is publish your SPA or PWA dist files in a docker container and maybe even push it to a private registry.

Instead of having to write a Dockerfile, pull some base OS, increase the size of the container image, add potential attack surfaces / vulnerabilities coming from those base OS images, you can wrap and embed it in a Go binary.

Install ko

Create a ko-build.sh in the project root

#!/bin/bash
ko login registry.domain.tld -u myuser -p mypassword
KO_DOCKER_REPO=registry.domain.tld/user/my-frontend ko build --platform=all

#!/bin/bash

ko login registry.domain.tld -u myuser -p mypassword

KO_DOCKER_REPO=registry.domain.tld/user/my-frontend ko build --platform=all

go mod init git.domain.tld/user/repo
touch main.go

1 2	go mod init git.domain.tld/user/repo touch main.go

and edit main.go and insert the following

package main

import (
	"embed"
	"io/fs"
	"log"
	"net/http"
	"strings"
)

//go:embed dist
var pwa embed.FS

//go:embed dist/index.html
var index embed.FS

var indexFile []byte

func init() {
	var e error
	indexFile, e = index.ReadFile("dist/index.html")
	if e != nil {
		log.Fatal(e.Error())
	}
}

func main() {
	root, e := fs.Sub(pwa, "dist")
	if e != nil {
		log.Fatal(e.Error())
	}
	log.Fatal(http.ListenAndServe(":8080", Handler(root)))
}

func Handler(root fs.FS) http.Handler {
	handler := http.FileServer(http.FS(root))

	return http.HandlerFunc(func(w http.ResponseWriter, req *http.Request) {
		_path := req.URL.Path

		// static files
		if strings.Contains(_path, ".") || _path == "/" {
			handler.ServeHTTP(w, req)
			return
		}
		w.Write(indexFile)
	})
}

package main

import (

"embed"

"io/fs"

"log"

"net/http"

"strings"

)

//go:embed dist

var pwa embed.FS

//go:embed dist/index.html

var index embed.FS

var indexFile []byte

func init() {

var e error

indexFile, e = index.ReadFile("dist/index.html")

if e != nil {

log.Fatal(e.Error())

}

func main() {

root, e := fs.Sub(pwa, "dist")

if e != nil {

log.Fatal(e.Error())

}

log.Fatal(http.ListenAndServe(":8080", Handler(root)))

}

func Handler(root fs.FS) http.Handler {

handler := http.FileServer(http.FS(root))

return http.HandlerFunc(func(w http.ResponseWriter, req *http.Request) {

_path := req.URL.Path

// static files

if strings.Contains(_path, ".") || _path == "/" {

handler.ServeHTTP(w, req)

return

}

w.Write(indexFile)

})

}

assuming your bundler, e.g. vite, places dist files in your project root’s dist dir (vite default),

dist
├── assets
│   ├── index-D-1oofZ3.css
│   └── index-DMGf-fk6.js
├── index.html
└── vite.svg

dist

├── assets

│ ├── index-D-1oofZ3.css

│ └── index-DMGf-fk6.js

├── index.html

└── vite.svg

If your dist files are in dist/pwa and your index file is at dist/pwa/index.html edit the lines accordingly.

This is effectively what would be in nginx:

	location / {
		try_files $uri $uri/ /index.html;
	}

location / {

try_files $uri $uri/ /index.html;

}

Your container exposes port 8080

Build and publish

bash ko-build.sh

1	bash ko-build.sh

Since you only need to write this once, you can copy the main.go to every project that requires it and adjust the ko-build.sh script.

Yes, this survives CTRL+F5 reloads. It routes everything through index.html unless it’s a static file that exists on the filesystem.

#spa #pwa #go #ko #docker #registry #build #publish

k8s delete pv or pvc first?

Short answer: Delete the pvc, then the pv.
From k8s v1.31 on if the external-csi-provisioner is installed (which it is with rook ceph) and the reclaim policy is Delete, if you delete the pvc, the pv is automatically deleted

#k8s #pv #pvc

Banned from entgo, why?

I wanted to create an issue, in github.com/ent/ent the size annotation doesn’t have any effect when used on a MySQL database.

I couldn’t create the issue, “unable to create issue”, and no further information.

So I said that I can’t create an issue in their discord.
Then I wrote, “So I’ve been banned. What for? Being to critical of Atlas?”

Without any response I was banned from the discord as well.

?!?

Because I don’t agree with giving them my schema information when I need to use it in a k8s context?

I don’t know because I never received a reason.

Seriously, I’ve had enough of those emotionally and mentally unstable mini dictators, banning people for personal entertainment or satisfying their inferiority complex.

Absolutely unacceptable behavior banning someone from their discord only for asking what’s wrong.

Ariel Mashraki need his head examined.

Update 21. Jan. 2025:
I created an issue with Atlas where I demanded the ban lifted or my contributions, issues, discussions and comments deleted.
That issue was deleted and I was banned from the Atlas repository.
I’m now going to file copyright and intellectural property violations with Github, also find a lawyer to sue them.
