Docker Compose: a nice way to set up a dev environment
|
||||
======
|
||||
|
||||
Hello! Here is another post about [computer tools that I’ve appreciated][1]. This one is about Docker Compose!
|
||||
|
||||
This post is mostly just about how delighted I was that it does what it’s supposed to do and it seems to work and to be pretty straightforward to use. I’m also only talking about using Docker Compose for a dev environment here, not using it in production.
|
||||
|
||||
I’ve been thinking about this kind of personal dev environment setup more recently because I now do all my computing with a personal cloud budget of like $20/month instead of spending my time at work thinking about how to manage thousands of AWS servers.
|
||||
|
||||
I’m very happy about this because previous to trying Docker Compose I spent two days getting frustrated with trying to set up a dev environment with other tools and Docker Compose was a lot easier and simpler. And then I told my sister about my docker-compose experiences and she was like “I KNOW, DOCKER COMPOSE IS GREAT RIGHT?!?!” So I thought I’d write a blog post about it, and here we are.
|
||||
|
||||
### the problem: setting up a dev environment
|
||||
|
||||
Right now I’m working on a Ruby on Rails service (the backend for a sort of computer debugging game). On my production server, I have:
|
||||
|
||||
* a nginx proxy
|
||||
* a Rails server
|
||||
* a Go server (which proxies some SSH connections with [gotty][2])
|
||||
* a Postgres database
|
||||
|
||||
|
||||
|
||||
Setting up the Rails server locally was pretty straightforward without resorting to containers (I just had to install Postgres and Ruby, fine, no big deal), but then I wanted send `/proxy/*` to the Go server and everything else to the Rails server, so I needed nginx too. And installing nginx on my laptop felt too messy to me.
|
||||
|
||||
So enter `docker-compose`!
|
||||
|
||||
### docker-compose lets you run a bunch of Docker containers
|
||||
|
||||
Docker Compose basically lets you run a bunch of Docker containers that can communicate with each other.
|
||||
|
||||
You configure all your containers in one file called `docker-compose.yml`. I’ve pasted my entire `docker-compose.yml` file here for my server because I found it to be really short and straightforward.
|
||||
|
||||
```
|
||||
version: "3.3"
|
||||
services:
|
||||
db:
|
||||
image: postgres
|
||||
volumes:
|
||||
- ./tmp/db:/var/lib/postgresql/data
|
||||
environment:
|
||||
POSTGRES_PASSWORD: password # yes I set the password to 'password'
|
||||
go_server:
|
||||
# todo: use a smaller image at some point, we don't need all of ubuntu to run a static go binary
|
||||
image: ubuntu
|
||||
command: /app/go_proxy/server
|
||||
volumes:
|
||||
- .:/app
|
||||
rails_server:
|
||||
build: docker/rails
|
||||
command: bash -c "rm -f tmp/pids/server.pid && source secrets.sh && bundle exec rails s -p 3000 -b '0.0.0.0'"
|
||||
volumes:
|
||||
- .:/app
|
||||
web:
|
||||
build: docker/nginx
|
||||
ports:
|
||||
- "8777:80" # this exposes port 8777 on my laptop
|
||||
```
|
||||
|
||||
There are two kinds of containers here: for some of them I’m just using an existing image (`image: postgres` and `image: ubuntu`) without modifying it at all. And for some I needed to build a custom container image – `build: docker/rails` says to use `docker/rails/Dockerfile` to build a custom container.
|
||||
|
||||
I needed to give my Rails server access to some API keys and things, so `source secrets.sh` puts a bunch of secrets in environment variables. Maybe there’s a better way to manage secrets but it’s just me so this seemed fine.
|
||||
|
||||
### how to start everything: `docker-compose build` then `docker-compose up`
|
||||
|
||||
I’ve been starting my containers just by running `docker-compose build` to build the containers, then `docker-compose up` to run everything.
|
||||
|
||||
You can set `depends_on` in the yaml file to get a little more control over when things start in, but for my set of services the start order doesn’t matter, so I haven’t.
|
||||
|
||||
### the networking is easy to use
|
||||
|
||||
It’s important here that the containers be able to connect to each other. Docker Compose makes that super simple! If I have a Rails server running in my `rails_server` container on port 3000, then I can access that with `http://rails_server:3000`. So simple!
|
||||
|
||||
Here’s a snippet from my nginx configuration file with how I’m using that in practice (I removed a bunch of `proxy_set_header` lines to make it more clear)
|
||||
|
||||
```
|
||||
location ~ /proxy.* {
|
||||
proxy_pass http://go_server:8080;
|
||||
}
|
||||
location @app {
|
||||
proxy_pass http://rails_server:3000;
|
||||
}
|
||||
```
|
||||
|
||||
Or here’s a snippet from my Rails project’s database configuration, where I use the name of the database container (`db`):
|
||||
|
||||
```
|
||||
development:
|
||||
<<: *default
|
||||
database: myproject_development
|
||||
host: db # <-------- this "magically" resolves to the database container's IP address
|
||||
username: postgres
|
||||
password: password
|
||||
```
|
||||
|
||||
I got a bit curious about how `rails_server` was actually getting resolved to an IP address. It seems like Docker is running a DNS server somewhere on my computer to resolve these names. Here are some DNS queries where we can see that each container has its own IP address:
|
||||
|
||||
```
|
||||
$ dig +short @127.0.0.11 rails_server
|
||||
172.18.0.2
|
||||
$ dig +short @127.0.0.11 db
|
||||
172.18.0.3
|
||||
$ dig +short @127.0.0.11 web
|
||||
172.18.0.4
|
||||
$ dig +short @127.0.0.11 go_server
|
||||
172.18.0.5
|
||||
```
|
||||
|
||||
### who’s running this DNS server?
|
||||
|
||||
I dug into how this DNS server is set up a very tiny bit.
|
||||
|
||||
I ran all these commands outside the container, because I didn’t have a lot of networking tools installed in the container.
|
||||
|
||||
**step 1**: find the PID of my Rails server with `ps aux | grep puma`
|
||||
|
||||
It’s 1837916. Cool.
|
||||
|
||||
**step 2**: find a UDP server running in the same network namespace as PID `1837916`
|
||||
|
||||
I did this by using `nsenter` to run `netstat` in the same network namespace as the `puma` process. (technically I guess you could run `netstat -tupn` to just show UDP servers, but my fingers only know how to type `netstat -tulpn` at this point)
|
||||
|
||||
```
|
||||
$ sudo nsenter -n -t 1837916 netstat -tulpn
|
||||
Active Internet connections (only servers)
|
||||
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
|
||||
tcp 0 0 127.0.0.11:32847 0.0.0.0:* LISTEN 1333/dockerd
|
||||
tcp 0 0 0.0.0.0:3000 0.0.0.0:* LISTEN 1837916/puma 4.3.7
|
||||
udp 0 0 127.0.0.11:59426 0.0.0.0:* 1333/dockerd
|
||||
```
|
||||
|
||||
So there’s a UDP server running on port `59426`, run by `dockerd`! Maybe that’s the DNS server?
|
||||
|
||||
**step 3**: check that it’s a DNS server
|
||||
|
||||
We can use `dig` to make a DNS query to it:
|
||||
|
||||
```
|
||||
$ sudo nsenter -n -t 1837916 dig +short @127.0.0.11 59426 rails_server
|
||||
172.18.0.2
|
||||
```
|
||||
|
||||
But – when we ran `dig` earlier, we weren’t making a DNS query to port 59426, we were querying port 53! What’s going on?
|
||||
|
||||
**step 4**: iptables
|
||||
|
||||
My first guess for “this server seems to be running on port X but I’m accessing it on port Y, what’s going on?” was “iptables”.
|
||||
|
||||
So I ran iptables-save in the container’s network namespace, and there we go:
|
||||
|
||||
```
|
||||
$ sudo nsenter -n -t 1837916 iptables-save
|
||||
.... redacted a bunch of output ....
|
||||
-A DOCKER_POSTROUTING -s 127.0.0.11/32 -p udp -m udp --sport 59426 -j SNAT --to-source :53
|
||||
COMMIT
|
||||
```
|
||||
|
||||
There’s an iptables rule that sends traffic on port 53 to 59426. Fun!
|
||||
|
||||
### it stores the database files in a temp directory
|
||||
|
||||
One nice thing about this is: instead of managing a Postgres installation on my laptop, I can just mount the Postgres container’s data directory at `./tmp/db`.
|
||||
|
||||
I like this because I really do not want to administer a Postgres installation on my laptop (I don’t really know how to configure Postgres), and conceptually I like having my dev database literally be in the same directory as the rest of my code.
|
||||
|
||||
### I can access the Rails console with `docker-compose exec rails_server rails console`
|
||||
|
||||
Managing Ruby versions is always a little tricky and even when I have it working, I always kind of worry I’m going to screw up my Ruby installation and have to spend like ten years fixing it.
|
||||
|
||||
With this setup, if I need access to the Rails console (a REPL with all my Rails code loaded), I can just run:
|
||||
|
||||
```
|
||||
$ docker-compose exec rails_server rails console
|
||||
Running via Spring preloader in process 597
|
||||
Loading development environment (Rails 6.0.3.4)
|
||||
irb(main):001:0>
|
||||
```
|
||||
|
||||
Nice!
|
||||
|
||||
### small problem: no history in my Rails console
|
||||
|
||||
I ran into a problem though: I didn’t have any history in my Rails console anymore, because I was restarting the container all the time.
|
||||
|
||||
I figured out a pretty simple solution to this though: I added a `/root/.irbrc` to my container that changed the IRB history file’s location to be something that would persist between container restarts. It’s just one line:
|
||||
|
||||
```
|
||||
IRB.conf[:HISTORY_FILE] = "/app/tmp/irb_history"
|
||||
```
|
||||
|
||||
### I still don’t know how well it works in production
|
||||
|
||||
Right now my production setup for this project is still “I made a digitalocean droplet and edited a lot of files by hand”.
|
||||
|
||||
I think I’ll try to use docker-compose to run this thing in production. My guess is that it should work fine because this service is probably going to have at most like 2 users at a time and I can easily afford to have 60 seconds of downtime during a deploy if I want, but usually something goes wrong that I haven’t thought of.
|
||||
|
||||
A few notes from folks on Twitter about docker-compose in production:
|
||||
|
||||
* `docker-compose up` will only restart the containers that need restarting, which makes restarts faster
|
||||
* there’s a small bash script [wait-for-it][3] that you can use to make a container wait for another service to be available
|
||||
* You can have 2 docker-compose.yaml files: `docker-compose.yaml` for DEV, and `docker-compose-prod.yaml` for prod. I think I’ll use this to expose different nginx ports: 8999 in dev and 80 in prod.
|
||||
* folks seemed to agree that docker-compose is fine in production if you have a small website running on 1 computer
|
||||
* one person suggested that Docker Swarm might be better for a slightly more complicated production setup, but I haven’t tried that (or of course Kubernetes, but the whole point of Docker Compose is that it’s super simple and Kubernetes is certainly not simple :) )
|
||||
|
||||
|
||||
|
||||
Docker also seems to have a feature to [automatically deploy your docker-compose setup to ECS][4], which sounds cool in theory but I haven’t tried it.
|
||||
|
||||
### when doesn’t docker-compose work well?
|
||||
|
||||
I’ve heard that docker-compose doesn’t work well:
|
||||
|
||||
* when you have a very large number of microservices (a simple setup is best)
|
||||
* when you’re trying to include data from a very large database (like putting hundreds of gigabytes of data on everyone’s laptop)
|
||||
* on Mac computers, I’ve heard that Docker can be a lot slower than on Linux (presumably because of the extra VM). I don’t have a Mac so I haven’t run into this.
|
||||
|
||||
|
||||
|
||||
### that’s all!
|
||||
|
||||
I spent an entire day before this trying to configure a dev environment by using Puppet to provision a Vagrant virtual machine only to realize that VMs are kind of slow to start and that I don’t really like writing Puppet configuration (I know, huge surprise :)).
|
||||
|
||||
So it was nice to try Docker Compose and find that it was straightforward to get to work!

Docker Compose:搭建开发环境的好办法
|
||||
======
|
||||
|
||||
大家好!我又写了一篇关于 [我最喜欢的电脑工具][1] 的文章。这一篇讲的是 Docker Compose!
|
||||
|
||||
这篇文章主要就是讲一讲我对 Docker Compose 有多么满意啦(不讨论它的缺点)!咳咳,因为它总能够完成它该做的,并且似乎总能奏效,更棒的是,它使用起来还非常简单。另外,在本文中,我只讨论我是怎么用 Docker Compose 来搭建开发环境的,而不涉及它在生产中的使用。
|
||||
|
||||
最近,我考虑了很多关于这种搭建个人开发环境的方式,原因是,我现在把所有的计算工作都搬到了一个私有云上,大概 20 美元/月的样子。这样一来,我就不用在工作的时候花时间去思考应该如何管理几千台 AWS 服务器了。
|
||||
|
||||
在此之前,我曾花了两天的时间,尝试使用其他的工具来尝试搭建一个开发环境,搭到后面,我实在是心累了。相比起来,Docker Compose 就简单易用多了,我非常满意。于是,我和妹妹分享了我的 `docker-compose` 使用经历,她略显惊讶:“是吧!你也觉得 Docker Compose 真棒对吧!” 嗯,我觉得我应该写一篇博文把过程记录下来,于是就有了你们看到的这篇文章。
|
||||
|
||||
### 我们的目标是:搭建一个开发环境
|
||||
|
||||
目前,我正在编写一个 Ruby on Rails 服务(它是一个计算机“调试”游戏的后端)。在我的生产服务器上,我安装了:
|
||||
|
||||
* 一个 Nginx 服务器
|
||||
* 一个 Rails 服务
|
||||
* 一个 Go 服务 (使用了 [gotty][2] 来代理一些 SSH 连接)
|
||||
* 一个 Postgres 数据库
|
||||
|
||||
在本地搭建 Rails 服务非常简单,用不着容器(我只需要安装 Postgres 和 Ruby 就行了,小菜一碟)。但是,我还想要把匹配 `/proxy/*` 的请求的发送到 Go 服务,其他所有请求都发送到 Rails 服务,所以我还要用到 Nginx。问题来了,在笔记本电脑上安装 Nginx 对我来说太麻烦了。
|
||||
|
||||
是时候使用 `docker-compose` 了!
|
||||
|
||||
### docker-compose 允许你运行一组 Docker 容器
|
||||
|
||||
基本上,Docker Compose 的作用就是允许你运行一组可以互相通信 Docker 容器。
|
||||
|
||||
你可以在一个叫做 `docker-compose.yml` 的文件中,配置你所有的容器。下面,我将贴上我为这个服务编写的 `docker-compose.yml` 文件(的全部内容),因为我觉得它真的很简洁、直接!
|
||||
|
||||
```
|
||||
version: "3.3"
|
||||
services:
|
||||
db:
|
||||
image: postgres
|
||||
volumes:
|
||||
- ./tmp/db:/var/lib/postgresql/data
|
||||
environment:
|
||||
POSTGRES_PASSWORD: password # yes I set the password to 'password'
|
||||
go_server:
|
||||
# todo: use a smaller image at some point, we don't need all of ubuntu to run a static go binary
|
||||
image: ubuntu
|
||||
command: /app/go_proxy/server
|
||||
volumes:
|
||||
- .:/app
|
||||
rails_server:
|
||||
build: docker/rails
|
||||
command: bash -c "rm -f tmp/pids/server.pid && source secrets.sh && bundle exec rails s -p 3000 -b '0.0.0.0'"
|
||||
volumes:
|
||||
- .:/app
|
||||
web:
|
||||
build: docker/nginx
|
||||
ports:
|
||||
- "8777:80" # this exposes port 8777 on my laptop
|
||||
```
|
||||
|
||||
这个配置包含了两种容器。对于前面两个容器,我不加修改地使用了既有的镜像(`image: postgres` 和 `image: ubuntu`)。对于后面两个,我不得不构建一个自定义容器镜像,其中, `build: docker/rails` 的作用就是告诉 Docker Compose,它应该使用 `docker/rails/Dockerfile` 来构建一个自定义容器。
|
||||
|
||||
我需要允许我的 Rails 服务访问一些 API 密钥和其他东西,因此,我使用了 `source secrets.sh`,它的作用就是在环境变量中预设一组密钥。
|
||||
|
||||
### 如何启动所有服务:先 “build” 后 “up”
|
||||
|
||||
我一直都是先运行 `docker-compose build` 来构建容器,然后再运行 `docker-compose up` 把所有服务启动起来。
|
||||
|
||||
你可以在 yaml 文件中设置 `depends_on`,这样你可以获得更多容器启动时的控制。不过,对于我的这些服务而言,启动顺序并不重要,所以我没有设置它。
|
||||
|
||||
### 使用网络通信也非常简单
|
||||
|
||||
有件很重要的事:容器之间得能够互相连接才行。Docker Compose 让这件事变得超级简单!假设我有一个 Rails 服务正在名为 `rails_server` 的容器中运行,端口是 3000,那么我就可以通过 `http://rails_server:3000` 来访问该服务。就是这么简单!
|
||||
|
||||
以下代码片段截取自我的 Nginx 配置文件,它是根据我的使用需求配置的(我删除了许多 `proxy_set_headers` 行,让它看起来更清楚):
|
||||
|
||||
```
|
||||
location ~ /proxy.* {
|
||||
proxy_pass http://go_server:8080;
|
||||
}
|
||||
location @app {
|
||||
proxy_pass http://rails_server:3000;
|
||||
}
|
||||
```
|
||||
|
||||
或者,你也看下面这个代码片段,它截取自我的 Rails 项目的数据库配置,我在其中使用了数据库容器的名称(`db`):
|
||||
|
||||
```
|
||||
development:
|
||||
<<: *default
|
||||
database: myproject_development
|
||||
host: db # <-------- 它会被“神奇地”解析为数据库容器的 IP 地址
|
||||
username: postgres
|
||||
password: password
|
||||
```
|
||||
|
||||
至于 `rails_server` 究竟是如何被解析成一个 IP 地址的,我还真有点儿好奇。貌似是 Docker 在我的计算机上运行了一个 DNS 服务来解析这些名字。下面是一些 DNS 查询记录,我们可以看到,每个容器都有它自己的 IP 地址:
|
||||
|
||||
```
|
||||
$ dig +short @127.0.0.11 rails_server
|
||||
172.18.0.2
|
||||
$ dig +short @127.0.0.11 db
|
||||
172.18.0.3
|
||||
$ dig +short @127.0.0.11 web
|
||||
172.18.0.4
|
||||
$ dig +short @127.0.0.11 go_server
|
||||
172.18.0.5
|
||||
```
|
||||
|
||||
### 是谁在运行这个 DNS 服务?
|
||||
|
||||
我(稍微)研究了一下这个 DNS 服务是怎么搭建起来的。
|
||||
|
||||
以下所有命令都是在容器外执行的,因为我没有在容器里安装很多网络工具。
|
||||
|
||||
**第一步:**:使用 `ps aux | grep puma`,找到我的 Rails 服务的进程 ID。
|
||||
|
||||
找到了,它是 `1837916`!感觉不错哦~
|
||||
|
||||
**第二步:**:找到和 `1837916` 运行在同一个网络命名空间的 UDP 服务。
|
||||
|
||||
我使用了 `nsenter` 来在 `puma` 进程的网络命令空间内运行 `netstat`(理论上,我猜想你也可以使用 `netstat -tupn` 来只显示 UDP 服务,但此时,我的手指头只会打出 `netstat -tulpn`)。
|
||||
|
||||
```
|
||||
$ sudo nsenter -n -t 1837916 netstat -tulpn
|
||||
Active Internet connections (only servers)
|
||||

||||

||||
tcp 0 0 0.0.0.0:3000 0.0.0.0:* LISTEN 1837916/puma 4.3.7
|
||||
udp 0 0 127.0.0.11:59426 0.0.0.0:* 1333/dockerd
|
||||
```
|
||||
|
||||
我们可以看到,此时有一个运行在 `59426` 端口的 UDP 服务,它是由 `dockerd` 运行的!或许它就是我们要找的 DNS 服务?
|
||||
|
||||
**第三步**:确定它是不是我们要找的 DNS 服务
|
||||
|
||||
我们可以使用 `dig` 工具来向它发送一个 DNS 查询:
|
||||
|
||||
```
|
||||
$ sudo nsenter -n -t 1837916 dig +short @127.0.0.11 59426 rails_server
|
||||
172.18.0.2
|
||||
```
|
||||
|
||||
奇怪,我们之前运行 `dig` 的时候,DNS 查询怎么没有发送到 `59426` 端口,而是发送到了 `53` 端口呢?这到底是怎么回事呀?
|
||||
|
||||
**第四步**:iptables
|
||||
|
||||
对于类似“这个服务似乎正运行在 X 端口上,但我却在 Y 端口上访问到了它,这是什么回事呢?”的问题,我的第一念头都是“一定是 iptables 在作怪”。
|
||||
|
||||
于是,我运行了容器的网络命令空间内运行了 `iptables-save`,果不其然,真相大白:
|
||||
|
||||
```
|
||||
$ sudo nsenter -n -t 1837916 iptables-save
|
||||
.... redacted a bunch of output ....
|
||||
-A DOCKER_POSTROUTING -s 127.0.0.11/32 -p udp -m udp --sport 59426 -j SNAT --to-source :53
|
||||
COMMIT
|
||||
```
|
||||
|
||||
在输出中有一条 iptables 规则,它将 `53` 端口的流量发送到了 `59426` 上。哈哈,真有意思!
|
||||
|
||||
### 数据库文件储存在一个临时目录中
|
||||
|
||||
这样做有一个好处:我可以直接挂载 Postgres 容器的数据目录 `./tmp/db`,而不需要在我的笔记本电脑上管理 Postgres 环境。
|
||||
|
||||
我很喜欢这种方式,因为我真的不想在笔记本电脑上,亲自管理一个 Postgres 环境(我也真的不知道该如何配置 Postgres)。还有就是,出于习惯,我更喜欢让开发环境的数据库和代码放在同一个目录下。
|
||||
|
||||
### 仅需一行命令,我就可以访问 Rails 控制台
|
||||
|
||||
管理 Ruby 的版本总是有点棘手,并且,即使我暂时搞定了它,我也总是有点担心自己会把 Ruby 环境搞坏,然后就要修它修个十年(夸张)。
|
||||
|
||||
(使用 Docker Compose)搭建好这个开发环境后,如果我需要访问 Rails <ruby>控制台<rt>console</rt></ruby>(一个交互式环境,加载了所有我的 Rails 代码),我只需要运行一行代码即可:
|
||||
|
||||
```
|
||||
$ docker-compose exec rails_server rails console
|
||||
Running via Spring preloader in process 597
|
||||
Loading development environment (Rails 6.0.3.4)
|
||||
irb(main):001:0>
|
||||
```
|
||||
|
||||
好耶!
|
||||
|
||||
### 小问题:Rails 控制台的历史记录丢失了
|
||||
|
||||
我碰到了一个问题:Rails 控制台的历史记录丢失了,因为我一直在不断地重启它。
|
||||
|
||||
不过,我也找到了一个相当简单的解决方案(嘿嘿):我往容器中添加了一个 `/root/.irbrc` 文件,它能够把 IRB 历史记录文件的保存位置,修改到一个不受容器重启影响的地方。只需要一行代码就够啦:
|
||||
|
||||
```
|
||||
IRB.conf[:HISTORY_FILE] = "/app/tmp/irb_history"
|
||||
```
|
||||
|
||||
### 我还是不知道它在生产环境的表现会怎么样
|
||||
|
||||
到目前为止,这个项目的生产环境搭建进度,还停留在“我制作了一个 digitalocean droplet(LCCT 译注:一种 Linux 虚拟机服务),并手工编辑了很多文件”的阶段。
|
||||
|
||||
嗯……我相信我以后会在生产环境中使用 docker-compose 来运行一下它的。我猜它能够会正常工作,因为这个服务很可能最多只有两个用户在使用,并且,如果我愿意,我可以容忍它在部署过程中有 60 秒的不可用时间。不过话又说回来,出错的往往是我想不到的地方。
|
||||
|
||||
推特网友提供了一些在生产中使用 docker-compose 的注意事项:
|
||||
|
||||
* `docker-compose up` 只会重启那些需要重启的容器,这会让重启速度更快。
|
||||
* 有一个 Bash 小脚本 [wait-for-it][3],你可以用它来让一个容器保持等待,直到另一个容器的服务可用。
|
||||
* 你可以准备两份 `docker-compose.yaml` 文件:用于开发环境的 `docker-compose.yaml` 和 用于生产环境的 `docker-compose-prod.yaml`。我想我会在分别为 Nginx 指定不同的端口:开发时使用 `8999`,生产中使用 `80`。
|
||||
* 人们似乎一致认为,如果你的项目是一台计算机上运行的小网站,那么 docker-compose 在生产中不会有问题。
|
||||
* 有个人建议说,如果愿意在生产环境搭建复杂那么一丢丢,Docker Swarm 就或许会是更好的选择,不过我还没试过(当然,如果要这么说的话,干嘛不用 Kubernetes 呢?Docker Compose 的意义就是它超级简单,而 Kubernetes 肯定不简单 :))。
|
||||
|
||||
Docker 似乎还有一个特性,它能够 [把你用 docker-compose 搭建的环境,自动推送到弹性容器服务(ESC)上][4],听上去好酷的样子,但是我还没有试过。
|
||||
|
||||
### docker-compose 会有不适用的场景吗
|
||||
|
||||
我听说 docker-compose 在以下场景的表现差强人意:
|
||||
|
||||
* 当你有很多微服务的时候(还是自己搭建比较好)
|
||||
* 当你尝试从一个很大的数据库中导入数据时(就像把几百 G 的数据存到每个人的笔记本电脑里一样)
|
||||
* 当你在 Mac 电脑上运行 Docker 时。我听说 Docker 在 macOS 上比在 Linux 上要慢很多(我猜想是因为它需要做额外的虚拟化)。我没有 Mac 电脑,所以我还没有碰到这个问题。
|
||||
|
||||
### 以上就是全部内容啦!
|
||||
|
||||
在此之前,我曾花了一整天时间,尝试使用 Puppet 来配置 Vagrant 虚拟机,然后在这个虚拟机里配置开发环境。结果,我发现虚拟机启动起来实在是有点慢啊,还有就是,我也不喜欢编写 Puppet 配置(哈哈,没想到吧)。
|
||||
|
||||
幸好,我尝试了 Docker Compose,它真好简单,马上就可以开始工作啦!
