篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了滑板nomad和prd那个好用相关的知识,希望对你有一定的参考价值。
参考技术A nomad比较好用。nomad适合入门级玩家去玩的一款滑板,属于入门级别的,适合新手。prd需要熟练的,控板能力强的。可以根据自己的熟练程度选择合适自己的。
Nomad由滑手IvanMoreno于2000年创立,是西班牙的第一个本土滑板品牌。Nomad灵感来自于nomadism一词,中文寓意游牧民,就像滑手们喜欢带着滑板四处旅行,与世界各地的滑手进行交流,发现并尝试新的滑板地形一样,品牌理念正是源于此意,属于中端档次。
通过 nomad 在 docker 中安装卷
【中文标题】通过 nomad 在 docker 中安装卷【英文标题】:Mounting volumes in docker via nomad 【发布时间】:2021-10-20 08:07:22 【问题描述】:我正在尝试通过 nomad 运行 docker 容器。该作业规范旨在运行带有 java docker 映像的 docker 容器。来自 localhost 路径的卷应该安装到 docker 容器上。该卷将包含一些 java 文件。容器应按照命令指定的方式编译 java 文件。
期望:java程序的编译应该完成,并且应该在容器和我的本地主机路径中创建一个类文件。
工作规范文件:
job "java"
datacenters = ["dc1"]
type = "service"
update
max_parallel = 1
healthy_deadline = "3m"
progress_deadline = "10m"
auto_revert = false
canary = 0
migrate
max_parallel = 1
health_check = "checks"
min_healthy_time = "10s"
healthy_deadline = "5m"
group "compile"
count = 1
service
name = "java-compile"
tags = ["java", "compile"]
restart
attempts = 2
interval = "30m"
delay = "15s"
mode = "fail"
ephemeral_disk
size = 300
task "java"
driver = "docker"
config
image = "adoptopenjdk/openjdk11"
mount
type = "bind"
target = "/java"
source = "/home/ninan/nomad/java"
readonly = false
bind_options
propagation = "rshared"
work_dir = "/java"
command = "javac Hello.java"
resources
cpu = 500 # 500 MHz
memory = 1024 # 256MB
目前它无法说出volumes are not enabled; cannot mount host path: "/home/ninan/nomad/java"

Nomad 服务器启动为 -
sudo nomad agent -dev -bind 0.0.0.0 -log-level INFO
如何启用卷挂载?
【问题讨论】:
【参考方案1】:您应该在 nomad 启动之前先创建卷路径,然后在您的 client.hcl
文件中添加以下配置:
host_volume "database-data"
path = "/srv/live/postgres-database/data/"
read_only = false
然后在你的工作规范中,
在group
节中定义音量:
volume "database-data"
type = "host"
read_only = false
source = "database-data"
然后最后在task
节中添加以下内容,使用定义的卷:
volume_mount
volume = "database-data"
destination = "/var/lib/postgresql/data" #<-- in the container
read_only = false
