docker - 部署Splunk Docker镜像无法登录

Question

我从repository README中学到，我正在使用splunk/splunk docker image和以下命令来构建和运行:

docker build --network=$DOCKER_NETWORK -t my-splunk .

docker run \
    --name=my-splunk \
    --network=$DOCKER_NETWORK \
    -p 8000:8000 \
    -e SPLUNK_START_ARGS="--accept-license" \
    -e SPLUNK_PASSWORD="1234" \
    --restart unless-stopped \
    -d my-splunk

当我在localhost:8000上打开浏览器时，按预期方式获得了Splunk登录页面，但是，当键入admin和1234时，出现了错误401:

No users exist. Please set up a user.

从容器中查看/opt/splunk/etc/system/local/user-seed.conf，内容看起来不错:

[user_info]
USERNAME = admin
PASSWORD = 1234

好吧，显然密码必须符合https://hub.docker.com/r/splunk/splunk/的某些默认要求:

For a basic standalone Splunk environment, run the following command:

$ docker run -d -p 8000:8000 -e 'SPLUNK_START_ARGS=--accept-license' -e 'SPLUNK_PASSWORD=' splunk/splunk:latest Note: The password supplied must conform to the default Splunk Enterprise password requirements*

将密码从“1234”更改为“12345678910”后，登录正常(仅默认要求，密码长度至少应为8个字符)。

由于创建用户的失败已被静音，并且仅在dockerhub中记录了此问题，而在github中没有记录，因此我将打开一个案例以通知他们。
