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

由 谁都会走 提交于 2021-02-11 08:10:44
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

How to pass flags to java process in Docker contatiner built by Cloud Native Buildpacks (CNB)

由 五迷三道 提交于 2021-02-11 07:23:56
问题 Normally when I create Docker image I do something like this: FROM openjdk:15-jdk-slim ARG version=undefined LABEL version=${version} WORKDIR / COPY build/libs/v2t-api-$version.jar /v2t-api.jar USER nobody VOLUME ["/tmp"] EXPOSE 8080 EXPOSE 8081 ENTRYPOINT ["sh", "-c", "exec java ${JAVA_OPTS} -jar v2t-api.jar"] So, when I start my container in for example kubernetes I can set JAVA_OPTS which defines how many memory is available for heap or how many CPUs are actually there.

How do you change default detach key sequence in docker?

由 坚强是说给别人听的谎言 提交于 2021-02-11 05:13:00
问题 Docker container's detach key sequence by default is control+q or control+p. There is an option to set key sequence when starting a container using --detach-keys "<sequence>" but I am looking for a permanent change. Is there a way to change this key sequence to something else? 回答1: Per user, you can configure this in the $HOME/.docker/config.json file. Add a json entry similar to: { "auths": { ... }, "detachKeys": "ctrl-x,x" } The "auths" line is just giving a relative location in the json,
