到目前为止，我正在使用java客户端并使用远程api进行有限的实现。我的目标是使用自动图像来旋转多个容器，然后动态地使这些容器直接访问具有开发人员代码的主机。在这种情况下，它是一个运行Tomcat和.war文件的容器。
我不想在图像中包含.war文件，因为这会创建数百个图像。通过命令行，我可以将.war复制到一个容器中，这可能没问题但是在远程api中似乎没有选项。理想情况下，我想为容器提供可用的挂载点，并且开发人员可以不断更新其代码。如果这可能会很好，但到目前为止我还没有找到合适的组合。我尝试过HostConfig：绑定：[“/ host / path：/ container / path”]显示在容器信息中，但似乎没有按照我的意愿行事。任何和所有的帮助将非常感激。
下面是我用来创建容器的java方法。
public int doIt(){
int ri = 0;
JSONObject object = new JSONObject();
JSONObject aObject = new JSONObject();
JSONObject bObject = new JSONObject();
JSONArray list = new JSONArray();
try {
object.put("Image", "test/tomcat");
aObject.put("/home/mkwalter/tomcat/webapps", new JSONObject());
object.put("Volumes", aObject);
list.add("/home/mkwalter/tomcat/webapps:/usr/local/tomcat/webapps");
bObject.put("Binds",list);
object.put("HostConfig", bObject);
System.out.println("object.toString before try " + object.toString());
} catch (Exception e) {
System.out.println(e);
}
try {
HttpClient httpClient = HttpClientBuilder.create().build(); //Use this instead
HttpPost request = new HttpPost("http://192.168.1.97:4243/containers/create?name=");
StringEntity params = new StringEntity(object.toString());
request.addHeader("content-type", "application/json");
request.setEntity(params);
HttpResponse response = httpClient.execute(request);
System.out.println("Response Code : "
+ response.getStatusLine().getStatusCode());
ri = response.getStatusLine().getStatusCode();
} catch (Exception ex){
System.out.println(ex);
}
return ri;
}
下面是对方法创建的容器的检查。

抱歉占用了这么多空间。
java创建的字符串在下面。
{"Image":"test\/tomcat","HostConfig":{"Binds":["\/home\/mkwalter\/tomcat\/webapps:\/usr\/local\/tomcat\/webapps"]},"Volumes":{"\/home\/mkwalter\/tomcat\/webapps":{}}}
回应代码：201
答案 0 :(得分：0)
您当前的JSON格式为
{
"Image": "test/tomcat",
"HostConfig": {
"Binds": [
"/home/mkwalter/tomcat/webapps:/usr/local/tomcat/webapps"
]
},
"Volumes": {
"/home/mkwalter/tomcat/webapps": {
}
}
}
您应该发布格式为
的请求{
"Image": "test/tomcat",
"HostConfig": {
"Binds": [
"/home/mkwalter/tomcat/webapps:/usr/local/tomcat/webapps"
]
},
"Volumes": {
"/usr/local/tomcat/webapps":{}
}
}
这是您需要修复此代码的更新
JSONObject object = new JSONObject();
JSONObject aObject = new JSONObject();
JSONObject bObject = new JSONObject();
JSONArray list = new JSONArray();
try {
object.put("Image", "test/tomcat");
aObject.put("/usr/local/tomcat/webapps", new JSONObject());
object.put("Volumes", aObject);
list.add("/home/mkwalter/tomcat/webapps:/usr/local/tomcat/webapps");
bObject.put("Binds",list);
object.put("HostConfig", bObject);
