注意上面由java.nio.file.AccessDeniedException引起的

。文件夹/elasticsearch/data
已存在，并且似乎像往常一样归属于travis:travis

我在这里需要帮助确定根本原因，并找到一个解决方案，希望它不涉及使用chown
或chmod
强制执行权限，并且在我的本地机器上也能工作（即没有硬编码的UID）。
默认情况下，Docker容器始终以root
用户身份运行。因此，所有正在运行的进程、共享卷、文件夹和文件都将归root
用户所有
如果您不手动创建共享文件夹，docker将创建它，它将归root
用户所有：
$ ls -la
total 16
drwxrwxr-x  3 ubuntu ubuntu 4096 Oct 19 23:02 .
drwxrwxr-x 14 ubuntu ubuntu 4096 Oct 19 21:57 ..
-rw-rw-r--  1 ubuntu ubuntu  534 Oct 19 21:58 docker-compose.yaml
drwxr-xr-x  3 root   root   4096 Oct 19 23:02 elasticsearch

$ ls -laR elasticsearch
elasticsearch:
total 12
drwxr-xr-x 3 root   root   4096 Oct 19 23:02 .
drwxrwxr-x 3 ubuntu ubuntu 4096 Oct 19 23:02 ..
drwxr-xr-x 2 root   root   4096 Oct 19 23:02 data

elasticsearch/data:
total 8
drwxr-xr-x 2 root root 4096 Oct 19 23:02 .
drwxr-xr-x 3 root root 4096 Oct 19 23:02 ..

这就是为什么要使用java.nio.file.AccessDeniedException

如果我们创建/elasticsearch/data
文件夹，并在容器启动之前（在docker compose up
命令之前）具有启动docker容器的用户权限，则可以避免此问题。对于您的特殊情况，它是：
before_install:
- mkdir -p elasticsearch/data
- docker-compose up -d
- docker-compose logs -f &
- wget -q --waitretry=1 --retry-connrefused -T 10 -O - http://127.0.0.1:9200
[...more stuff here...]

当我意识到我对docker卷的理解根本错误时，我解决了这个问题。我认为为了持久化数据，我需要将数据文件夹映射到本地文件系统。但事实上，所需要的只是将其映射到docker数据卷！这样做完全避开了许可问题
在展示解决方案之前，我只想说我调查了本地映射的/elasticsearch/data
文件夹的用户映射问题。我发现：在travis主机上，文件夹如下所示：
$ ls -la ./elasticsearch/data
total 8
drwxrwxr-x 2 travis travis 4096 Oct 20 18:21 .
drwxrwxr-x 3 travis travis 4096 Oct 20 18:21 ..
-rw-rw-r-- 1 travis travis    0 Oct 20 18:21 .gitkeep

在ES容器内：
elasticsearch_1  | total 8
elasticsearch_1  | drwxrwxr-x 2          2000 2000 4096 Oct 20 18:16 .
elasticsearch_1  | drwxrwxr-x 1 elasticsearch root 4096 Sep 26 14:20 ..
elasticsearch_1  | -rw-rw-r-- 1          2000 2000    0 Oct 20 18:16 .gitkeep

其中，uid
2000是主机的travis
用户。我不知道在这一点上我改变了方向之后需要做什么-除了手动chown
之类的东西
对于我的例子，更好的解决方案是创建一个docker数据容器并将其映射到ES数据
