docker image build Dockerfile

docker-compse.yml 内で定義 　go のimage
image:xxx/xxx ->直接pull して使う

imageを調査する
　履歴調査　docker image history image_name
　構成調査　docker image inspect image_name

build a image from dockerfile
　docker build --help 

Dockerfile 原則
　1. container from Dockerfile  is ephemeral
　2. one container one process (easy to scale  horizontally)
　3. minimize container layer ( use one-line command. one command one layer)

   RUN apt-get update && apt-get install -y \
  bzr \
  cvs \
  git \
  mercurial \
  subversion

　4. docker build dockerfile_path　(---no-cache=true)
    　run commands in dockerfile to create layer.
    　but first to search cache (sha256のchecksumがあり）あれば、使う。

docker mac performance

docker use linux kernel almost as native, so performance is well.
in mac or windows, things are different. there is no linux kernel.
so some helper needed.

docker-machine:   a tool to install docker in virtual machine. Dockerized hosts (hosts with Docker Engine on them).

 docker for Mac/Windows:  even still run a virtual machine (super hidden ).with its own hypervisor “hyperkit” and shared file system “osxfs”. Unfortunately, “osxfs” wasn’t very fast.

 but in many cases, realtime host-virtual consistence is not necessary.
So options come
 host first docker run -v hostDir1:/virtualDir1:cached  
 virtual first docker run -v hostDir1:/virtualDir1:delegated
 realTime run -v hostDir1:/virtualDir1:consistent

docker run exec

「docker run」コマンドは、コンテナを作成して起動するコマンド。
docker run  -it image_name "/bin/bash"
他のTabでdocker ps
Containerが増える。
実質は：
     docker create image_name
    docker start image_name
「docker exec」コマンドは、起動中のコンテナ内で、指定したコマンドを実行するコマンド。
docker ps
docker exec -it container_id "/bin/bash"




docker-run options image_name init_command
-- name (起動されたContainerに名前）
-- rm (Container終了時削除）
-v  fromHostSrc:toContainerTarget-e   env parameters
-d  run in backend

 docker-sync　start サンプル：
docker run --rm -v "dir1:/app_sync" -v "dir2:/host_sync" -e HOST_VOLUME=/host_sync -e APP_VOLUME=/app_sync -e TZ=$(basename $(dirname `readlink /etc/localtime`))/$(basename `readlink /etc/localtime`) -e UNISON_SRC="/host_sync" -e UNISON_DEST="/app_sync" -e UNISON_ARGS=" -ignore='Name .git' -ignore='Name .idea' -ignore='Name mysql_data' -prefer /host_sync -numericids -auto -batch" -e UNISON_WATCH_ARGS="-repeat watch"  --name backend-service eugenmayer/unison:2.51.2.1 /usr/local/bin/precopy_appsync

試しに一回起動してすぐ削除されたので、また起動
docker run -d -v "dir1:/app_sync" -v "dir2:/host_sync" -e HOST_VOLUME=/host_sync -e APP_VOLUME=/app_sync -e TZ=$(basename $(dirname `readlink /etc/localtime`))/$(basename `readlink /etc/localtime`) -e UNISON_SRC="/host_sync" -e UNISON_DEST="/app_sync" -e UNISON_ARGS=" -ignore='Name .git' -ignore='Name .idea' -ignore='Name mysql_data' -prefer /host_sync -numericids -auto -batch" -e UNISON_WATCH_ARGS="-repeat watch"  --name backend-service eugenmayer/unison:2.51.2.1

MacOS bad support on HFS/APFS







 MacOS/OSX has very bad filesystem events support on HFS/APFS, watching the file-system for changes using unox or fswatch was causing a heavy CPU load. This CPU load is very significant, even on modern high-end CPUs (like a i7 4770k / 3.5GHz).

Removing packages installed with go get







juse delete the source and package



麻烦，要是有一个命令就好了，找一下







It's safe to just delete the source directory and compiled package file. Find the source directory under $GOPATH/src and the package file under $GOPATH/pkg/<architecture>, for example: $GOPATH/pkg/windows_amd64.





example

go get github.com/golang/mock/mockgen





go clean -i github.com/golang/mock/mockgen



The -i flag causes clean to remove the corresponding installed

archive or binary (what 'go install' would create).



The -n flag causes clean to print the remove commands it would execute,

but not run them.



The -r flag causes clean to be applied recursively to all the

dependencies of the packages named by the import paths.





The -x flag causes clean to print remove commands as it executes them.



不知道安装的packagePath的话，找一下$GOPATH/pkg/windows_amd64啥的
