使用Elastic Docker镜像进行端口转发
我试图用这个docker图像testingdocker。 事情应该是直截了当的。 但事实并非如此。
我运行这个命令来启动容器：
sudo docker run -d -p 9200:9200 -p 9300:9300 elasticsearch -Des.node.name="ElasticTestNode" 然后我尝试在我的主机中运行这个命令：
# curl -XPUT "http://localhost:9200/movies/movie/3" -d' { "title": "To Kill a Mockingbird", "director": "Robert Mulligan", "year": 1962, "genres": ["Crime", "Drama", "Mystery"] }'
我期待看到某种成功的信息。 相反，命令只是卡住了 。 没有输出，也没有停下来。 我必须按Ctrl-X才能退出。
跑出想法，我在Docker里面开了一个bash shell，并testing了一下：
sudo sudo docker exec -i -t some-docker-id /bin/bash root@somehash:/usr/share/elasticsearch# curl -XPUT "http://localhost:9200/movies/movie/3" -d' { "title": "To Kill a Mockingbird", "director": "Robert Mulligan", "year": 1962, "genres": ["Crime", "Drama", "Mystery"] }' {"_index":"movies","_type":"movie","_id":"3","_version":1,"_shards":{"total":2,"successful":1,"failed":0},"created":true}root@somehash:/usr/share/elasticsearch#
这是成功的。 我做错了什么？
更新：尝试在我的主机上的另一个命令：
$ curl -XPUT -v "http://localhost:9200/movies/movie/3" -d' { "title": "To Kill a Mockingbird", "director": "Robert Mulligan", "year": 1962, "genres": ["Crime", "Drama", "Mystery"] }' * Trying 127.0.0.1... * Connected to localhost (127.0.0.1) port 9200 (#0) > PUT /movies/movie/3 HTTP/1.1 > Host: localhost:9200 > User-Agent: curl/7.43.0 > Accept: */* > Content-Length: 139 > Content-Type: application/x-www-form-urlencoded > * upload completely sent off: 139 out of 139 bytes
困在这里…

Docker的端口映射似乎有时会失败。 我多次遇到这个问题。 相同的testing脚本在启动时工作，而不在另一个上。
有一件事情是一致的，如果事情在一次启动的时候坏了，那么每次我重新启动Docker映像时都会失败。 它甚至在我放弃容器并用图像开始一个新的之后仍然失败。 这似乎是docker守护程序的一个问题。
我解决这个问题的方法是停止所有容器并重新启动docker守护进程：
sudo docker stop $(docker ps -a -q) sudo systemctl restart docker sudo docker start $(docker ps -a -q)
这个对我有用。 希望有人会觉得有帮助。
