Docker – 设置环境变量

设置环境变量

--env 或者-e指定docker的环境变量 key=value

<span class="token function">docker</span> run -e <span class="token assign-left variable">POSTGRES_USER</span><span class="token operator">=</span><span class="token string">'postgres'</span> -e <span class="token assign-left variable">POSTGRES_PASSWORD</span><span class="token operator">=</span><span class="token string">'密码'</span> <span class="token punctuation">..</span>. <span class="token function">docker</span> run --env <span class="token assign-left variable">env</span><span class="token operator">=</span>dev -d -p <span class="token number">8888</span>:8080 balance <span class="token function">docker</span> run -e spring.datasource.url<span class="token operator">=</span><span class="token string">'jdbc:mysql://10.0.0.17:3306/laker'</span> -d -p <span class="token number">8080</span>:8080 lak er-java:v1 
<span class="token function">docker</span> run -e <span class="token assign-left variable">POSTGRES_USER</span><span class="token operator">=</span><span class="token string">'postgres'</span> -e <span class="token assign-left variable">POSTGRES_PASSWORD</span><span class="token operator">=</span><span class="token string">'密码'</span> <span class="token punctuation">..</span>. <span class="token function">docker</span> run --env <span class="token assign-left variable">env</span><span class="token operator">=</span>dev -d -p <span class="token number">8888</span>:8080 balance <span class="token function">docker</span> run -e spring.datasource.url<span class="token operator">=</span><span class="token string">'jdbc:mysql://10.0.0.17:3306/laker'</span> -d -p <span class="token number">8080</span>:8080 lak er-java:v1 
docker run -e POSTGRES_USER='postgres' -e POSTGRES_PASSWORD='密码' ... docker run --env env=dev -d -p 8888:8080 balance docker run -e spring.datasource.url='jdbc:mysql://10.0.0.17:3306/laker' -d -p 8080:8080 lak er-java:v1 

查看环境变量

方式一 docker inspect 命令来查看

<span class="token function">docker</span> inspect 容器id 
<span class="token function">docker</span> inspect 容器id 
docker inspect 容器id 

如果是Windows的话可以用可视化界面，原理一样。

方式二 docker exec 容器id env
