docker xrdp遠端桌面

yku Leave a comment

在docker裡安裝rdp，這裡有二個範例，一個是ubuntu為範本製作的，另一個使用rockylinux為基底，基本上可使用注音及倉頡輸入法、中文字型及firefox browser。

catyku/UbuntuXRDP: with chinese input ime and firefox (github.com)

catyku/RockyLinux9XRdpDocker: RockyLinux 9 install xrdp to docker (github.com)

rockylinux (centos)為基底的image，很多UI應用程式都可以使用yum 直接安裝。

而以ubuntu為基底的image，因為ubuntu本身UI應用程式都需要使用snap都支持，安裝上就相對比較麻煩。

docker run -d --name containerName -p 3389:3389 catyku/ubuntu-xrdp:22.04 createUser password rootYesNo
docker run -d --name containerName -p 3389:3389 catyku/rockylinuxrdp createUser password rootYesNo

之後就可以使用遠端桌面連入docker裡了

建立maven及docker private repositories

使用docker images sonatype/nexus3來快速建立環境，nexus3是opensource，可自行編譯使用。不過有部份外掛套件是需要付費使用的，像是Azure Blob Storage，此時可以選擇付費使用Nexus3 pro版本。

建立docker-compose.yml (記得建立一個nexus-data目錄來存放blob資料)

version: "3.5"

services:
  mariadb:
    container_name: nexus3
    image: sonatype/nexus3
    environment:
      TZ: Asia/Taipei
    ports:
      - "127.0.0.1:8081:8081"
    volumes:
      - ./nexus-data:/nexus-data
    restart: unless-stopped
    logging:
      options:
        max-size: 512M
#    deploy:
#      resources:
#        limits:
          #cpus: '0.50'
#          memory: 1024M

啟動docker

sudo docker-compose up -d

設定virtualhost來對應Nexus3服務

<VirtualHost *:80> 
        ServerName nexus3.yourdomain 
        ProxyRequests off 
        ProxyPreserveHost On 
        ProxyPass "/" "http://127.0.0.1:8081/" 
        ProxyPassReverse "/" "http://127.0.0.1:8081/" 
</VirtualHost>

取得admin預設密碼，來登入設定

nano nexus-data/admin.password

新增repository

選擇新增一個maven host及docker host

如何在 Rocky Linux 8 上安裝 Docker 和 Docker-Compose

yku Leave a comment

眾所周知，Docker容器是IT世界中技術需求量很大。在 Docker Container協助下，開發人員和基礎設施管理員可以打包他們的應用程式及其依賴項目，並可以在一個computer將其deploy，換到另一個computer中一樣可行。

以下將介紹如何逐步在Rocky Linux 8(AlamLinux)上安裝Docker和Docker Compose。

Step 1 安裝所需套件及repository

 sudo yum install -y yum-utils
 sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

Step 2 安裝docker 及docker compose

sudo yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin

Step 3 啟動docker

sudo systemctl start docker

Step 4 測試一下

sudo docker run hello-world

設定啟動Linux自動啟動

sudo systemctl enable docker
