boot2docker

问题 I'm having an issue storing the output of docker run -it -d -p 43211:3000 --name appname -h hostname -v $PWD/local_dir:/root/remote_dir repo/imagename in a BASH varibale. I tried `backticks`, I also tried running it like the official docs say BASH_VAR=$(docker run ...) , I even tried storing the output in a file with docker run --...>$FILE_DESCRIPTOR , but no luck storing the error situation, the situation when the name is already used by another container, like so: $ FATA[0000] Error

问题 I am new to Docker, using boot2docker on Windows 7. While I was trying to configure Docker build through spotify maven plugin, I was asked to set below env variables : DOCKER_HOST DOCKER_CERT_PATH DOCKER_TLS_VERIFY Configuration was successful but am not sure What does the DOCKER_TLS_VERIFY and DOCKER_CERT_PATH variables do ? 回答1: As mentioned in the README: By default, boot2docker runs docker with TLS enabled . It auto-generates certificates and stores them in /home/docker/.docker inside the

问题 I tried this on my Windows 10 machine: Dockerfile: From microsoft/nanoserver CMD ["echo", "Hello World"] PS C:\FSD\Docker\Trial1> docker build -t lea/leatest .

问题 I use docker logs [container-name] to see the logs of a specific container. Is there an elegant way to clear these logs? 回答1: From this question there's a one-liner that you can run: echo "" > $(docker inspect --format='{{.LogPath}}' <container_name_or_id>) I'm not a big fan of modifying Docker's files directly with this, a truncate command, or log rotate, since each are external to docker. The external log deletion could happen while docker is writing json formatted data to the file,

问题 I am working on a task that involves building a docker image with centOs as its base using a Dockerfile . One of the steps inside the dockerfile needs http_proxy and https_proxy ENV variables to be set in order to work behind the proxy. As this Dockerfile will be used by multiple teams having different proxies, I want to avoid having to edit the Dockerfile for each team. Instead I am looking for a solution which allows me to pass ENV variables at build time, e.g., sudo docker build -e http

问题 On a Mac, how do you mount a volume to a Docker container? On my linux box, this is easy. All I need to do is something like -v /src/webapp:/opt/webapp when running the container.

问题 I'm hainvg trouble with docker and volume size. I'm running docker-machine with three containers. The one giving me trouble is the MySQL container which has a data-only container for persistance. When I try to import a mysql file, mysql complains that the table is full, which really means that the disk is out of space. Looking at the system, I see the problem, but don't know how to correct it: _ _ ____ _ _ | |__ ___ ___ | |_|___ \ __| | ___ ___| | _____ _ __ | '_ \ / _ \ / _ \| __| __) / _` |
