问题 The following command works perfectly and the riak service starts as expected: docker run --name=riak -d -p 8087:8087 -p 8098:8098 -v $(pwd)/schemas:/etc/riak/schema basho/riak-ts The local schemas directory is mounted successfully and the sql file in it is read by riak. However if I try to mount the riak's data or log directories, the riak service does not start and timeouts after 15 seconds: docker run --name=riak -d -p 8087:8087 -p 8098:8098 -v $(pwd)/logs:/var/log/riak -v $(pwd)/schemas:

问题 I am new to docker and Kubernetes, I am trying to create a container having tomcat7/Java7 so that I could deploy my webapps into it. The only concern I have are the tomcat/conf config files, which have details of database connections , threadpool , Java Memory etc. What I want is to copy these files from Kubernetes server to docker-container and place them at right places, while starting the container. P.S: I don't want to do it via enviroment variables, as they are going to be huge in

问题 I am using the "plain" postgresql:alpine docker image, but have to schedule a database backup daily. I think this is a pretty common task. I created a script backup and stored in the container in /etc/periodic/15min , and made it executable: bash-4.4# ls -l /etc/periodic/15min/ total 4 -rwxr-xr-x 1 root root 95 Mar 2 15:44 backup I tried executing it manually, that works fine. My problem is getting crond to run automatically. If I exec docker exec my-postgresql-container crond , the deamon is

问题 I'm running AWS ECS cluster with EC2 instances and I want a command to scale up the tasks to 1 running instance and then after some time when I do not need it I want to scale it down to 0. This should destroy the underlying EC2 instance to avoid charges. I'm not using Fargate as it is not in free tier. what I'm currently using to scale up to one and start running it: ecs-cli scale --capability-iam --size 1 --cluster myEC2clusterName --region us-east-1 aws ecs run-task --cluster

问题 I have two containers, a apache-php container, and a mysql db container. I am trying to get my php script to query my sql database. I am however receiving the following errors; Fatal error: Uncaught PDOException: PDO::__construct(): php_network_getaddresses: getaddrinfo failed: Name or service not known AND Fatal error: Uncaught PDOException: SQLSTATE[HY000] [2002] No such file or directory when toggling the host address, i think i am missing something fundamental to docker and this is

问题 There are two containers A and B. Once container A starts, one process will be executed, then the container will stop. Container B is just an web application (say expressjs). Is it possible to kickstart A from container B ? 回答1: It is possible to grant a container access to docker so that it can spawn other containers on your host. You do this by exposing the docker socket inside the container, e.g: docker run -v /var/run/docker.sock:/var/run/docker.sock --name containerB myimage ... Now, if

问题 As a docker beginner, I have built a swarm cluster on 5 Linux server. (docker version 17.12.0-ce) But when I create a service, I see docker service ps command shows "pulling image failed" error="pull access denied for registry.xxxx.xxx . I'm using a private registry which should be use docker login at first.

问题 I start a mysql container and change the config file inside a container, in this case is /etc/mysql/my.cnf . And restart container. Maybe something wrong with that config file and the container cannot start. How can I edit that config file when the container has been shutdown? 回答1: A container is immutable, your changes and conf are gone. You should use a Dockerfile to build a custom image and include my.cnf. It can be easily done, create a folder, create my.cnf in it and a Dockerfile with
