配置Docker守护程序端口以启用Docker API

我试图按所述配置：

cat /etc/docker/daemon.json { "debug": "true", "hosts": "tcp://127.0.0.1:5000" } # Service docker status docker stop/waiting # service docker start start: Job failed to start Docker version: 17.04

我启用了来检查启动Docker服务的问题，并从以下位置的日志中了解到/var/log/upstart/docker.log：

Waiting for /var/run/docker.sock unable to configure the Docker daemon with file /etc/docker/daemon.json: json: cannot unmarshal string into Go value of type bool

是什么配置文件有问题daemon.json吗？

建议更改后的问题：

cat /etc/docker/daemon.json
{
"debug": true,
"hosts": "tcp://127.0.0.1:5000"
}

错误：

Waiting for /var/run/docker.sock unable to configure the Docker daemon with file /etc/docker/daemon.json: json: cannot unmarshal string into Go value of type []string

所以我将其更改为：

cat /etc/docker/daemon.json
{
"debug": true,
"hosts": ["tcp://127.0.0.1:5000"]
}

和调试日志：

回答：

这是Dan Low提供的答案的补充。

配置Docker守护程序端口有两种方法：

在文件中配置：

DOCKER_OPTS="-H tcp://127.0.0.1:5000 -H unix:///var/run/docker.sock"

在配置：
```
{
```
“debug”: true,
“hosts”: [“tcp://127.0.0.1:5000”, “unix:///var/run/docker.sock”]
}

配置端口后，重新启动Docker服务。

如果未配置Docker默认套接字，则可能会出现问题中提到的类似问题，即。

注意：但不要同时在配置文件中进行配置。可能会发生以下错误：

Waiting for /var/run/docker.sock unable to configure the Docker daemon with file /etc/docker/daemon.json: the following directives are specified both as a flag and in the configuration file: hosts: (from flag: [tcp://127.0.0.1:5000 unix:///var/run/docker.sock], from file: tcp://127.0.0.1:5000)

其原因将两个的和

是用户端口使得接入到

而默认套接字启用CLI。如果/etc/default/docker文件中未提及默认端口[unix：///var/run/docker.sock]，则可能会发生以下错误：

# docker ps Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

该错误不是因为Docker容器未运行，而是因为未启用默认Docker套接字。

这适用于Docker 17.04版本，并且可能因不同版本的Docker而有所不同。

以上是配置Docker守护程序端口以启用Docker API 的全部内容，来源链接： utcz.com/qa/406984.html
