 为Go程序构建一个最小的容器

我想使用Buildah从头开始构建一个小的容器映像，以运行Go应用程序。
除了应用程序本身 ，需要包含哪些其他库等。 我认为glibc是必需的还有其他吗？</ p>总而言之，我想问的是“ Linux上经过编译的Go应用需要什么外部依赖？” </ p>

I want to build a tiny container image from scratch using Buildah to run a Go app. Apart from the app itself, what other libraries etc need to be included. I am thinking that glibc is needed  is there anything else?
So in summary, I think I am asking "what are all the external dependencies that a compiled Go app needs on Linux?"
 duan19740319 ldd命令应该告诉您动态链接的可执行文件需要哪些共享库。如前所述，可能还会有文件被引用/需要（例如，在/etc中）。

 dongza6247 编译后的二进制Go应用程序是独立的，因此没有依赖性。如果使用syscall加载外部库，或者打开并读取外部文件，则显然将需要这些文件，但除此之外，将不需要任何东西。

@Dave C gave the information to correctly answer this. Using ldd with the test app returned:
[bryon@localhost resttest]$ ldd restest
linuxvdso.so.1 (0x00007fff139fe000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007fbad6ce2000)
libc.so.6 => /lib64/libc.so.6 (0x00007fbad691f000)
/lib64/ldlinuxx8664.so.2 (0x00007fbad6f02000)
[bryon@localhost resttest]$
So for those looking to build a minimal container with Buildah, the BASH script to generate it would look like this:
#!/bin/bash
#
# Run this shell script after you have run the command: "buildah unshare"
#
git clone https://github.com/bryonbaker/resttest.git
cd resttest
go build restest.go
container=$(buildah from scratch)
mnt=$(buildah mount $container)
mkdir $mnt/bin
mkdir $mnt/lib64
buildah config workingdir /bin $container
buildah copy $container restest /bin/restest
buildah copy $container /lib64/libpthread.so.0 /lib64
buildah copy $container /lib64/libc.so.6 /lib64
buildah copy $container /lib64/ldlinuxx8664.so.2 /lib64
buildah config port 8000 $container
#
# This step is not working properly.
# Need to run with podman p 8000:8000 entrypoint /bin/restest restest:latest
buildah config entrypoint /bin/restest $container
buildah commit format docker $container restest:latest
This generates a 14MB container for a simple microservice! There are no additional files to be worrying about for vulnerabilities etc.
I have a small defect I can't work out on entrypoints so I am overriding the entrypoint on start, but to test it run:
podman p8000:8000 entrypoint /bin/restest restest:latest
Then just type the following in a Terminal session:
curl http://localhost:8000
So thanks Dave C!
我假设您已将应用程序依赖项包含在docker映像中。</ p>
您不会 需要任何外部依赖关系来构建docker映像。 只需Go的基础映像就足以在Linux机器上构建和运行。</ p>
＃从最新的Go基础映像开始
FROM golang：latest
＃设置当前 容器内的工作目录
WORKDIR / app
＃复制go mod和求和文件
COPY go.mod go.sum ./
#下载所有依赖项。 如果go.mod和go.sum文件未更改，则依赖项将被缓存
RUN go mod下载
</ code> </ pre>

I am assuming you have included the app dependencies in your docker image.
You won't require any external dependency to build a docker image. Just base image from Go is sufficient to build and run on Linux machines.
# Start from the latest Go base image
FROM golang:latest
# Set the Current Working Directory inside the container
WORKDIR /app
# Copy go mod and sum files
COPY go.mod go.sum ./
# Download all dependencies. Dependencies will be cached if the go.mod and go.sum files are not changed
RUN go mod download

 doujiu8918 那是对的。 二进制文件是在外部构建的。 一个简单的微服务，在TCP端口上侦听和发送。 我只想将其容器化。 Buildah具有强大的功能来生成最少的图像但是要做到这一点，您需要了解需要包括哪些类型的依赖项。 （因此提出问题）。

Containers _course
20171130Problem Description At a container terminal, containers arrive from the hinterland, one by one, by rail, by road, or by small ships. The containers are piled up as they arrive. Then the huge cargo ships arrive, each one capable of carrying thousands of containers. The containers are loaded into the ships that will bring them to far away shores. Or the other way round, containers are brought in over sea, piled up, and transported to the hinterland one by one. Anyway, a huge parking lot is needed, to store the containers waiting for further transportation. ![](http://acm.hdu.edu.cn/data/images/3499_1.png) Building the new container terminal at the mouth of the river was a good choice. But there are disadvantages as well. The ground is very muddy, and building on firm ground would have been substantially cheaper. It will be important to build the parking lot not larger than necessary. A container is 40 feet long and 8 feet wide. Containers are stacked, but a stack will be at most five containers high. The stacks are organized in rows. Next to a container stack, and between two container stacks (along the long side of the containers) a space of 2 feet is needed for catching the containers. Next to a row of stacks, and between two stacks (along the short side of the containers) a space of 4 feet is needed for the crane that lifts the containers. All containers are placed in the same direction, as the cranes can not make turns on the parking lot. The parking lot should be rectangular. Given the required capacity of the parking lot, what will be the best dimension for the parking lot? In the first place the area should be minimal. The second condition is that the parking lot should be as square as possible. Below you see a plan for a parking lot with a capacity of 8 stacks. Two rows of four containers each turns out to be the best solution here, with a total area of 92 × 42 = 3864. A parking lot with 8 container stacks.

Depot _course
20170811Description A Finnish high technology company has a big rectangular depot. The depot has a worker and a manager. The sides of the depot, in the order around it, are called left, top, right and bottom. The depot area is divided into equalsized squares by dividing the area into rows and columns. The rows are numbered starting from the top with integers 1,2,... and the columns are numbered starting from the left with integers 1,2,... The depot has containers, which are used to store invaluable technological devices. The containers have distinct identification numbers. Each container occupies one square. The depot is so big, that the number of containers ever to arrive is smaller than the number of rows and smaller than the number of columns. The containers are not removed from the depot, but sometimes a new container arrives. The entry to the depot is at the top left corner. The worker has arranged the containers around the top left corner of the depot in such a way that he will be able to find them by their identification numbers. He uses the following method. Suppose that the identification number of the next container to be inserted is k (container k, for short). The worker travels the first row starting from the left and looks for the first container with identification number larger than k. If no such container is found, then container k is placed immediately after the rightmost of the containers previously in the row. If such a container l is found, then container l is replaced by container k, and l is inserted to the following row using the same method. If the worker reaches a row having no containers, the container is placed in the leftmost square of that row. Suppose that containers 3,4,9,2,5,1 have arrived to the depot in this order. Then the placement of the containers at the depot is as follows. 1 4 5 2 9 3 The manager comes to the worker and they have the following dialogue: Manager: Did container 5 arrive before container 4? Worker: No, that is impossible. Manager: Oh, so you can tell the arrival order of the containers by their placement. Worker: Generally not. For instance, the containers now in the depot could have arrived in the order 3,2,1,4,9,5 or in the order 3,2,1,9,4,5 or in one of 14 other orders. As the manager does not want to show that the worker seems much smarter, he goes away. You are to help the manager and write a program which, given a container placement, counts all possible orders in which they might have arrived. Input Your program is to read from standard input. The first line contains one integer R: the number of rows with containers in them. The following R lines contain information about rows 1,...,R starting from the top as follows. First on each of those lines is an integer M: the number of containers in that row. Following that, there are M integers on the line: the identification numbers of the containers in the row starting from the left. All container identification numbers I satisfy 1 <= I <= 50. Let N be the number of containers in the depot, then 1 <= N <= 13. Output Your program is to write to standard output. The output contains an integer: the number of possible orders in which containers might have arrived. An arrival order should be counted only once. Sample Input 3 3 1 4 5 2 2 9 1 3 Sample Output 16

Just Pour the Water _course
20170226Shirly is a very clever girl. Now she has two containers (A and B), each with some water. Every minute, she pours half of the water in A into B, and simultaneous pours half of the water in B into A. As the pouring continues, she finds it is very easy to calculate the amount of water in A and B at any time. It is really an easy job :). But now Shirly wants to know how to calculate the amount of water in each container if there are more than two containers. Then the problem becomes challenging. Now Shirly has N (2 <= N <= 20) containers (numbered from 1 to N). Every minute, each container is supposed to pour water into another K containers (K may vary for different containers). Then the water will be evenly divided into K portions and accordingly poured into anther K containers. Now the question is: how much water exists in each container at some specified time? For example, container 1 is specified to pour its water into container 1, 2, 3. Then in every minute, container 1 will pour its 1/3 of its water into container 1, 2, 3 separately (actually, 1/3 is poured back to itself, this is allowed by the rule of the game). Input Standard input will contain multiple test cases. The first line of the input is a single integer T (1 <= T <= 10) which is the number of test cases. And it will be followed by T consecutive test cases. Each test case starts with a line containing an integer N, the number of containers. The second line contains N floating numbers, denoting the initial water in each container. The following N lines describe the relations that one container(from 1 to N) will pour water into the others. Each line starts with an integer K (0 <= K <= N) followed by K integers. Each integer ([1, N]) represents a container that should pour water into by the current container. The last line is an integer M (1<= M <= 1,000,000,000) denoting the pouring will continue for M minutes. Output For each test case, output contains N floating numbers to two decimal places, the amount of water remaining in each container after the pouring in one line separated by one space. There is no space at the end of the line. Sample Input 1 2 100.00 100.00 1 2 2 1 2 2 Sample Output 75.00 125.00
