无法创建/etc/nginx/nginx.conf:目录不存在和启动容器导致“exec:"supervisord“:$PATH 中找不到可执行文件" [英] cannot create /etc/nginx/nginx.conf: Directory nonexistent and starting container caused "exec: "supervisord": executable file not found in $PATH"
问题描述
我正在构建 docker 映像以使用 uwsgi/nginx 部署烧瓶应用程序.
I am building docker image to deploy flask app with uwsgi/nginx.
这里是为相同的创建 docker 容器的相关文件
Here are relevant file for to create a docker container for same
Dockerfile

当我尝试在 trell-ds-framework 目录中构建 docker 映像时(使用命令 docker build -t ds_backend .
,我在 Dockerfile 的第 13/17 行收到以下错误
when I am trying to build the docker image in trell-ds-framework directory (using command docker build -t ds_backend .
, I am getting following error on line 13/17 of Dockerfile
Step 13/17 : RUN echo "daemon off;" >> /etc/nginx/nginx.conf
---> Running in 1ee5628a4bc2
/bin/sh: 1: cannot create /etc/nginx/nginx.conf: Directory nonexistent
The command '/bin/sh -c echo "daemon off;" >> /etc/nginx/nginx.conf' returned a non-zero code: 2
我检查了这个 /etc/nginx/nginx.conf
文件是否存在于我的虚拟机中.
I checked this /etc/nginx/nginx.conf
file exists in my virtual machine.
我正在从这个 教程 - 部署中获得帮助使用 docker 的带有 uwsgi/nginx 的烧瓶应用程序似乎正在工作.但就我而言,它给出了那个错误.
I am taking help from this Tutorial - Deploy flask app with uwsgi/nginx using docker which seems to be working. But in my case its giving that error.
按照评论说明,我可以成功构建 docker 映像.现在我在下面收到此错误.
After following comments instruction I could build docker image successfully. Now I am getting this error below.
docker: Error response from daemon: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: "supervisord": executable file not found in $PATH": unknown.
谁能帮帮我.提前致谢.
Can anybody help me out here. Thanks in advance.
PS:我对这些东西很陌生.任何线索都非常感谢.
PS: I am very new to these things. Any leads highly appreciated.
推荐答案
由于几乎不可能使用评论管理答案,我将在此处发布 supervisor_app.conf
文件的前景:
Since managing answers with comments is nearly impossible, I'll post the outlook of the supervisor_app.conf
file here:
[program:nginx]
command = /usr/sbin/nginx -g "daemon off;"
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0
我认为这是你需要的.
我刚刚看到关于未找到主管的评论.看来你还没有在 Dockerfile 中安装它.添加方法如下:
I just saw the comment about supervisor not being found. It seems that you haven't installed it in Dockerfile. Here's how to add it:
apt-get install -y supervisor
您可以在其中一个步骤中仅添加包名称,如下所示:
You can add just the package name in one of the steps, like this:
RUN apt-get install -y ca-certificates supervisor
请注意,您已经有了该行,只是没有 supervisor
.
Note that you already have that line, just without supervisor
.
根据@thsutton 的回答,您还需要添加 nginx
包,就像 supervisor
一样.
As per @thsutton's answer, you also need to add nginx
package, the same way you did for supervisor
.
