So I have two nginx server in a kubernetes cluster. I want that one nginx server acts as a reverse proxy for the other that serves my phpmyadmin files.

For accessing my phpmydadmin from the first server, the user has to type: https://mynginx.example/phpmyadmin From that I want my nginx server to rewrite the URI before he proxy pass with replacing /phpmyadmin by /.

I write this for now

      location                /phpmyadmin {
            rewrite           /phpmyadmin(/.*) $1 break;
            proxy_pass        https://phpmyadmin.default.svc.cluster.local:5000;
      }

But actually when it returns me 404 error and when I saw logs on nginx that serves phpmyadmin I see:

19 open() "/var/www/localhost/htdocs/phpmyadmin/phpmyadmin" failed (2: No such file or directory)

It doesn't seem to replace my /phpmyadmin by /.

All my config file is:

server {
        listen                  80 default_server;
        listen                  [::]:80 default_server;

        return                  301 https://$host$request_uri;
}

server {
      listen                  443 ssl default_server;
      root                    /www;
      index                   index.html;

      ssl_certificate         /tls/tls.crt;
      ssl_certificate_key     /tls/tls.key;

      location                /phpmyadmin {
            rewrite           /phpmyadmin(/.*) $1 break;
            proxy_pass        https://phpmyadmin.default.svc.cluster.local:5000;
      }

      location                ~ /wordpress(.*) {
            return            307 $scheme://$host:5050$1;
      }
}

So I actually want to start my minikube cluster with a special directory mounted on it, on /data. This directory contains my db datas.

For this I try:

minikube start \
--driver=docker \
--extra-config=apiserver.service-node-port-range=1-35000 \
--disk-size=5000mb \
--mount \
--mount-string="${PWD}/srcs/mysql/datas:/data"

Actually options --mount and --mount-string="${PWD}/srcs/mysql/datas:/data" doesn't seem to works. No warning or error outputs are displayed but when I connect onto the machine and list files onto /data nothing appears. My directory is not mounted.

If I mount the directory with: minikube mount ${PWD}/srcs/mysql/datas:/data it works and I can list my data in /data. (But I really want to launch it at startup and now what I'm doing wrong).

So this is my Dockerfile:

FROM alpine

RUN apk add --update --upgrade --no-cache mysql mysql-client

RUN rm -rf /etc/my.cnf /etc/mysql/* /etc/mysql.d/ && \
mkdir -p /var/lib/mysql /var/run/mysqld && \
chown -R mysql /var/lib/mysql /run/mysqld && \
chgrp -R mysql /var/lib/mysql /run/mysqld && \
mysql_install_db --user=mysql --ldata=/var

EXPOSE 3306

USER mysql

CMD ["sh", "mysqld_safe --data=/var"]

My issue is that when I run the container with the image it does not find mysqld_safe. But when I run the command manually like this: docker run mysql mysqld_safe --data=/var it works ! I try to change the dockerfile with: CMD ["sh", "cat -"] to see if the problem is with the mysqld_safe command but same issue here, it does not find cat except when I run it with docker run mysql cat -.

Is the problem come from busybox on alpine, or from PATH ? I have no idea for now and I require you help.
