How to link two containers using docker-compose

问题 At the moment I have two containers which I build from an image and then link the two: For example: #mysql docker build -t my/mysql docker-mysql docker run -p 3306:3306 --name mysql -d my/mysql:latest #webapp docker build -t my/tomcat:7.0 tomcat/7.0 docker run -d --link mysql --name tomcat7 my/tomcat:7.0 Since I'm linking the webapp container with mysql container, the webapp container gets a MYSQL_PORT_3306_TCP_ADDR environment variable created. I use this environment variable to then connect

Localhost redirecting to localhost/tutorial

由 别来无恙 提交于 2021-02-11 09:08:33
问题 Yo! I am having an issue with my localhost after installing Docker Desktop. It automatically redirects to localhost/tutorial. I believe that is for the "beginner" container that comes with docker desktop, however even after removing it, and having other containers running, or even if docker is completely turned off, it still automatically redirects, which leads me to believe the issue is something with Windows. I've checked my hosts file on windows and can't find anything wrong, but in case

Docker execute ant script after tomcat starts?

由 陌路散爱 提交于 2021-02-11 08:56:10
问题 Dockerfile works correctly for tomcat. After tomcat starts, I have to trigger ant scripts. catalina.sh is started from a separate run.sh file. So, Dockerfile has CMD ["/tmp/run.sh"] The run.sh file has below lines: catalina.sh run antscript Tomcat starts but ant scripts are not called. I also tried other possibilities like: catalina.sh run && antscripts tomcat starts but antscripts are not triggered Is there a way that I can call the ant scripts automatically after tomcat starts? I dont want

How to execute something as a root user (initially) for an otherwise non-root user container?

由 可紊 提交于 2021-02-11 08:14:42
问题 I want to sync the host machine's user/group with the docker machine to enable (developers) to edit the files inside or outside the container. There are some ideas like this: Handling Permissions with Docker Volumes which creates a new user. I would like to try a similar approach, but instead of creating a new user, I would like to modify the existing user using usermod : usermod -d /${tmp} docker # avoid `usermod` from modifying permissions automatically. usermod -u "${HOST_USER_ID}" docker
