containers

问题 I'm learning Docker and experimenting by installing Drupal. The process is to create 2 containers with one running Apache and the other running MySQL. I have the following docker-compose.yml file: version: '3' services: d8: container_name: d8 image: drupal build: . ports: - "8585:80" links: - d8mysql:mysql d8mysql: container_name: d8mysql image: mysql restart: always environment: MYSQL_ROOT_PASSWORD: password MYSQL_PASSWORD: password MYSQL_DATABASE: drupal MYSQL_USER: user ports: - "3306:3306

问题 I am trying to build a Apache WebDAV private cloud server. All my files will be in /usr/John/ directory and I can mount this location for the container to use. The problem is that I will also add new files via this server, but whatever I try they stay only within the container. Is there a way to reflect the same new files also in the host directory (/usr/John/)? I could do a recurrent job to go into this container and CP all files to the host directory but it's not a very elegant solution.

问题 I am running a flink docker image with the following configuration. version: '2.1' services: jobmanager: build: . image: flink volumes: - .:/usr/local/lib/python3.7/site-packages/pyflink/lib hostname: "jobmanager" expose: - "6123" ports: - "8081:8081" command: jobmanager environment: - JOB_MANAGER_RPC_ADDRESS=jobmanager taskmanager: image: flink volumes: - .:/usr/local/lib/python3.7/site-packages/pyflink/lib expose: - "6121" - "6122" depends_on: - jobmanager command: taskmanager links: -

问题 Have a site with MANY horizontally scrolling DIV containers. On one of the containers we want it to scroll to a certain position onLoad. Recommendations to what the best solution is? To complicate it a little more, the container is vertically far down (i.e. below the fold) on the page and would rather not have the onLoad result in having the page scroll vertically down to this container, merely have this specific container scrolled horizontally and nothing else. Is this also possible? Many

问题 I'm a beginner C++ programmer so there are language constructs that I don't understand which prevents me from understanding map's API (for your reference, here) More to the point, some questions: How do I change the internal sorting scheme of map so that, given that we're working with map::<string, ...> , the key values are sorted alphabetically? More specifically about the map::key_comp , is it a define-and-forget thing where once we define what it means for two elements of the same type to

问题 I have read how the containers are assigned the containers IDs: How the docker container id is generated How is the docker ID uniqueness verified? And in which pool is it unique? Among all exited, among all running, among all deleted/removed, among all ever created by a specific docker service? I was wondering whether the container ID is a reusable value, since it comes from a random number, how likely is it that a new container will have exactly the same container ID as another one (exited,

问题 I am wondering why there is no STL function that deletes an element from a vector by swapping it to the end and then removing it. Is there a better data structure than std::vector if you don't care about the actual order of elements and still want very fast traversal? Note that using std::remove and std::erase is not the same because this is linear time instead of constant time as the order has to be preserved. 回答1: You can use std::partition instead of std::remove / std::remove_if : Keep

问题 I'm currently developing Quarkus applications and need therefore a CI Pipeline + Container Registry. As containerization through docker isn't working (docker daemon - priviliged mode) I want to use Jib, which is already supported by Quarkus. Command in Pipeline: - mvn clean package -Dquarkus.container-image.push=true -Dquarkus.container-image.registry="https://$registry" -Dquarkus.container-image.username=$username -Dquarkus.container-image.password=$deployToken -Dquarkus.container-image.name
