海外TECH	DEV Community	Step-by-step to learn and optimize Dockerfile	https://dev.to/kevwan/step-by-step-to-learn-and-optimize-dockerfile-5a69	Step by step to learn and optimize Dockerfile BackgroundI worked around the clock and overtime to develop the simplest Go Hello world application and although I just ran a print and quit my boss also asked me to go live with the only application I could write The project layout is as follows ├ーgo mod└ーhello gohello go code as follows package mainfunc main println hello world And the boss asked for docker deployment to make us look up to date First tryAfter visiting some friends for the martial arts I found that it would be good to compile the whole process into docker and after a bit of work I got the following Dockerfile FROM golang alpineWORKDIR buildCOPY hello go RUN go build o hello hello goCMD hello To build the image docker build t hello v Done let s get a closer look docker run it rm hello v ls l buildtotal rwxr xr x root root Mar hello rw r r root root Mar hello goAll my code is packed into the image it looks like I can t write bad code otherwise the ops girl will laugh at me if she read my code We look at what s the size of the mirror it is said that the larger image the slower to pull docker docker images grep hellohello v ee minutes ago MBWow MB did docker build make the Go program become Java Let s see why it s so large Look we ve got MB before we run the first instruction WORKDIR that s a bit fierce Anyway let s run it and see docker run it rm hello vhello world No problem at least it works Second tryAfter a lot of research and some advices from friends we found that the base image we were using was too big docker images grep golanggolang alpine da days ago MBAnd my friend told me that I could compile the code first and then copy it in without the huge base image but that s easier said than done so I put some effort into it and the final Dockerfile looks like this FROM alpineWORKDIR buildCOPY hello CMD hello Try running docker build t hello v gt ERROR COPY hello s gt COPY hello failed to compute cache key hello not found not foundNo hello was not found I forgot to compile hello go first come again go build o hello hello goThen run docker build t hello v no problem take two steps and try docker run it rm hello vstandard init linux go exec user process caused exec format errorFailed Well the format is not right so our development machine is not linux ah again GOOS linux go build o hello hello goRerun docker build finally done hurry up and run docker run it rm hello vhello world No problem let s see the content and size docker run it rm hello v ls l buildtotal rwxr xr x root root Mar helloThere is only hello executable inside no more worrying about people despising my code docker images grep hellohello v ddfc seconds ago MBhello v aceb minutes ago MBWow MB absolutely Look we only got MB in front of the first command WORKDIR happy Third tryAfter a bit of showing off someone actually despised me and said that it is now popular to build in multiple stages so what is wrong with the second way After thinking about it I found that we need to be able to build a docker image from Go code which is divided into three steps compile the Go code natively if it involves cgo cross platform compilation will be more troublesomebuild the docker image with the compiled executablewrite a shell script or makefile to make these steps available via a single commandA multi stage build puts it all into a Dockerfile no source code leaks no scripting to compile across platforms and a minimal image I finally wrote the following Dockerfile no one line more no one line less FROM golang alpine AS builderWORKDIR buildADD go mod COPY RUN go build o hello hello goFROM alpineWORKDIR buildCOPY from builder build hello build helloCMD hello The first FROM starts by building a builder image to compile the executable hello in and the second From starts by copying the executable hello from the first image and using the smallest possible base image alpine to keep the final image as small as possible as to The reason why we don t use the smaller scratch is that scratch really has nothing so we don t even have a chance to look at it if there s a problem and alpine is only MB so it won t have much impact on our service And I ll talk about generating the images from scratch later in this article Let s run it and verify that docker run it rm hello vhello world No problem as expected Let s see how the size is docker images grep hellohello v febe hours ago MBhello v ddfc hours ago MBhello v aceb hours ago MB The image size is exactly the same as the second method And look at the contents of the image shell docker run it rm hello v ls l buildtotal rwxr xr x root root Mar helloalso has only one executable hello file perfect It s basically the same as the second final image but we ve simplified the process to only a Dockerfile and run one command so I don t need to go through all the obscure shell and makefile God s work is doneSo far my teammates thought it was perfect and gave me a lot of praise However every time I write such a Dockerfile I still feel quite annoying so I wrote a tool let me show it shell install it first go install github com zeromicro go zero tools goctl latest write a Dockerfile with one command goctl docker go hello go Done Look at the generated Dockerfile dockerfileFROM golang alpine AS builderLABEL stage gobuilderENV CGO ENABLED RUN apk update no cache amp amp apk add no cache tzdataWORKDIR buildADD go mod ADD go sum RUN go mod downloadCOPY RUN go build ldflags s w o app hello hello goFROM alpineRUN apk update no cache amp amp apk add no cache ca certificatesCOPY from builder usr share zoneinfo America New York usr share zoneinfo America New YorkENV TZ America New YorkWORKDIR appCOPY from builder app hello app helloCMD hello A few the points to understand are cgo is disabled by defaultRemoved the debug message ldflags s w to reduce the image sizeInstalled ca certificates so that using TLS certificates is not a problemtzdata is installed in the builder image and only the required timezone is copied in the final imageautomatically set the local time zone so that we see New York time in the containerLet s look at the size of the image built with this auto generated Dockerfile shell docker images grep hellohello v baece hours ago MBhello v febe hours ago MBhello v ddfc hours ago MBhello v aceb hours ago MBIt s slightly larger because we copied ca certificates and tzdata Verify that Let s see what s in the image shell docker run it rm hello v ls l apptotal rwxr xr x root root Mar helloAlso only the hello executable and the file size has been reduced from KB to KB run it and see shell executableshell docker run it rm hello vhello world And you can specify the base image as scratch when generating the Dockerfile so the image is smaller but you can t log in directly via sh shell goctl docker base scratch go hello goThe size is also really small shell docker images grep hellohello v deedd seconds ago MBhello v baece hours ago MBhello v febe days ago MBhello v ddfc days ago MBhello v aceb days ago MB And look what s in the mirrorYou can provide the options platform linux amd or platform linux arm to docker build for generating the docker images of different OS and ARCH Okay okay no more Dockerfile I m going to learn new skills Project address	2022-03-22 05:40:59
