The date of The author version note
2021-03-24 dingbin V1.0

In daily development, C++ programmers inevitably encounter changes to computers, servers and other things. It is too heavy to rebuild and build the C++ development environment, which requires a lot of unnecessary and precious time. Vim’s YouCompleteme (YCM for short) plug-in can realize the function of automatic complete jump in C/C++ language, and is one of the necessary tools for C/C++ code editing by Vim. However, the actual installation of YCM is extremely complex, relying not only on the Python dynamic link library, but also on certain high-level versions of GCC and clang, or clangd and cmake, etc. Preparing these precomponents is also time-consuming and laborious. In view of this, this paper introduces a new way of playing and gives practical operation details as well as directly available Docker mirror-image results. That is, build a Docker mirror-image of YouCompleteme, a C++ completion jump plug-in based on Vim, and complete the building of C++ development environment on any machine with one key. The specific operation method is described as follows.

Environment to prepare

Time: 2021-03-24

CentOS Linux Release 7.5.1804 (Core), 8-core 12G

Create the underlying Docker image

Consider installing the latest version of Vim and YouCompleteme plug-ins at the current time. Reference website YouCompleteMe installation method for vim/GCC/clang/clangd/cmake/python under higher version to install successfully. We were making Docker images, so it was impossible to pick a very old base OS. Referring to the advice on YCM’s official website, we chose Ubuntu 20.04 LTS for the basic OS. Direct ready-made image files at hub.docker.com. The following three configuration files should be prepared for the configuration file.

Place the above 4 files in a directory and execute the command on any x86_64 machine where Docker is installed:

Docker build -- no-cache-t ycm-base:1.0

Create a local Docker image named: ycm-base:1.0

The author of this article has created a working YCM base image as described above and uploaded it to hub.docker.com as APOLLO008 / VIM8-YCM :3.0. The address is: https://hub.docker.com/repository/docker/apollo008/vim8-ycm-customize-user readers can be directly through the docker command: Docker pull apollo008/vim8-ycm:3.0 Just download the image and use it locally.

Create a Docker image of the custom user

The above docker image is created for user root. If you log in with the root account to edit a file in the docker container, it must be owned by the root user, so that other users outside the container do not have permission to edit or read the file. The solution is that based on the basic Vim-YCM image above, the user can create a YCM Docker image with his/her user name (especially UID) in the local Docker environment quickly, and then access the Docker container locally as that specific user. The reason is divided into two containers, because the basic container production time, cut may rely on the external network, resulting in the installation is difficult to succeed, so make good upload to the public mirror warehouse, different users in the mirror based on customized their own specific UID and Username of the local mirror, the operation steps are as follows. Dockerfile contents are as follows:

From apollo008/vim8-ycm:3.0 MAINTAINER dingbin [email protected] WORKDIR /root ARG APP_UID ARG APP_GID ARG APP_USER ARG  APP_GROUP RUN set -ex && apt-get install -y sudo openssh-server && \ groupadd -o -g ${APP_GID} ${APP_GROUP} && \ useradd -m -s /bin/bash -o -u ${APP_UID} -g ${APP_GID} ${APP_USER} && \ mkdir -p /etc/sudoers.d && \ echo root:123456 | chpasswd && \ echo ${APP_USER}:123456 | chpasswd && \ echo "${APP_USER} ALL=(ALL) NOPASSWD: ALL" > /etc/sudoers.d/${APP_USER} && \ chmod 0440 /etc/sudoers.d/${APP_USER} && \ cp /root/.vim /home/${APP_USER}/ -rf && \ cp /root/.vimrc /home/${APP_USER}/ -rf && \ cp /root/.ycm_extra_conf.py /home/${APP_USER}/ -rf && \ chown -R ${APP_USER}:${APP_GROUP} /home/${APP_USER}/.vim && \ chown -R ${APP_USER}:${APP_GROUP} /home/${APP_USER}/.vimrc && \ chown -R ${APP_USER}:${APP_GROUP} /home/${APP_USER}/.ycm_extra_conf.py COPY --chown=${APP_USER}:${APP_GROUP} Dockerfile /home/${APP_USER}/ COPY --chown=${APP_USER}:${APP_GROUP} .bashrc /home/${APP_USER}/ WORKDIR /home/${APP_USER} USER ${APP_USER} CMD vim

The Docker image with built-in VIM8.1 and YCM is Ubuntu 20.04 LTS as of 2021.03.22 the latest version of Vim and YCM. The corresponding configuration in ~/. Vimrc has been improved, including a more reasonable and beautiful color scheme. The effect is shown below.



Create a Docker image of your own user name such as work/user.

docker build –no-cache -t myycm:latest –build-arg APP_USER=work –build-arg APP_GROUP=work –build-arg APP_UID=1000 –build-arg APP_GID=1001 .

The recommended usage after mirroring is generated is: docker run -itd –name ycm1 -v hostPath:InDockerPath myycm:latest /bin/bash docker exec -it ycm1 /bin/bash Then execute the Vim xxx.cpp edit file on the interactive bash inside the Docker container. Avoid frequent opening of Docker Container, which is slow.
