<p>If I start the service using docker,It should look like this:</p>

<pre><code>docker run -e PARAMS="--spring.datasource.url=jdbc:mysql://mysql-service.example.com/xxl-job?Unicode=true&amp;characterEncoding=UTF-8 --spring.datasource.username=root --spring.datasource.password=&lt;mysql-password&gt;" -p 8180:8080 -v /tmp:/data/applogs --name xxl-job-admin  -d xuxueli/xxl-job-admin:2.0.2
</code></pre>

<p>now I am running it in kubernetes(v1.15.2) cluster,how to pass the parameter into pod's container? I am trying to pass parameter like this:</p>

<pre><code>"name": "xxl-job-service",
        "image": "xuxueli/xxl-job-admin:2.0.2",
        "args": [
          "--spring.datasource.url=jdbc:mysql://mysql-service.ttt208.com/xxl-job?Unicode=true&amp;characterEncoding=UTF-8 --spring.datasource.username=root --spring.datasource.password=&lt;mysql-password&gt;"
        ],
</code></pre>

<p>but it seem do not work,it throw :</p>

<pre><code>19:19:55.563 logback [xxl-job, admin JobFailMonitorHelper] ERROR c.x.j.a.c.t.JobFailMonitorHelper - &gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt; xxl-job, job fail monitor thread error:{}

<p>what should I do to run this service success? I am sure the database username and password correct.</p>

Dolphin
<p>Dockers <code>-e</code> or <code>--env</code> sets an environment variable. </p>

<p>The equivalent in a Kubernetes <a href="https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.17/#podspec-v1-core" rel="nofollow noreferrer">pod spec</a> is the <a href="https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.17/#container-v1-core" rel="nofollow noreferrer">containers <code>env</code> field</a></p>

<pre><code>  env:
  - name: PARAMS
    value: ' --spring.datasource.url=jdbc:mysql://mysql-service.example.com/xxl-job?Unicode=true&amp;characterEncoding=UTF-8 --spring.datasource.username=root --spring.datasource.password=&lt;mysql-password&gt;'
