Question

我一直在努力尝试将我的Golang应用程序部署到AWS EB几天。

我正尝试使用eb cli通过我的app文件夹中的Preconfigured Docker - Go 1.4 running on 64bit Debian/2.9.2命令在EB服务器eb deploy上部署我的应用程序。

几秒钟后，我收到一条错误消息，指出我的应用程序因为错误而未部署。看看eb-activity.log，我在这里可以看到：

            /usr/src/go/src/github.com/randomuser/private-repo/app (from $GOROOT)
            /go/src/github.com/randomuser/private-repo/app (from $GOPATH)

我认为当服务器尝试安装应用程序时出现问题，似乎它正试图从我在github上的私人仓库中检索...

我将我的app子包引用为github.com/randomuser/private-repo/subpackage我认为这就是为什么它的行为。

有没有办法部署我的所有代码，强制我的私人仓库在GOROOT src / github.com / randomuser / private-repo /中填充，所以服务器不必尝试获取它？

我没有从亚马逊文档（多包应用程序）或Github中找到任何正确的示例。

我错过了什么吗？有更好的解决方案吗？

另一方面，我也尝试直接部署我编译的二进制文件（创建一个文件夹，我只放置二进制文件，压缩它并将其上传到ebs env）但是它既没有用...也许这个选项需要另一个env配置（如果是，哪一个？）。

感谢您的帮助:)

以下是我的server.go

的内容

package main

import (
    "flag"
    "fmt"
    "net/http"

    "github.com/randomuser/private-repo/errors"
    "github.com/randomuser/private-repo/services"
)

func main() {
    // getting env from command line
    // env is either prod, preprod or dev
    // by default, env is prod
    env := flag.String("env", "prod", "environment: prod, preprod or dev")
    flag.Parse()

    ...
    router.To("GET,HEAD", "/ping", func(c *routing.Context) error {
       c.Abort() // skip all other middlewares/handlers
       return c.Write("OK " + app.Version)
    })
    ...
    // Serve on port 5000

我的Dockerfile内容：

FROM golang:1.4.2-onbuild

ADD . /go/src/github.com/randomuser/private-repo
RUN go install github.com/randomuser/private-repo

EXPOSE 5000

ENTRYPOINT /go/bin/private-repo

我终于成功了。

所以我创建了一个全新的eb应用程序（没有docker）。然后我发现我的应用程序无法以某种方式检索控制台中设置的env变量... 所以我做的是我强制env变量在启动时使用build.sh脚本从我的生产配置文件传递到我的应用程序，见下文：

#!/bin/bash -xe
# See http://tldp.org/LDP/abs/html/options.html
# -x -> Print each command to stdout before executing it, expand commands
# -e -> Abort script at first error, when a command exits with non-zero status
#   (except in until or while loops, if-tests, list constructs)

# $GOPATH isn't set by default, nor do we have a usable Go workspace :'(
GOPATH="/var/app/current"
APP_BUILD_DIR="$GOPATH/src/to-be-defined"     # We will build the app here
APP_STAGING_DIR="/var/app/staging"            # Current directory
DEP_VERSION="v0.3.2"                          # Use specific version for stability
ENV_VAR_PREFIX="TO_BE_DEFINED_"

# Install dep, a Go dependency management tool, if not already installed or if
# the version does not match.
if ! hash dep 2> /dev/null ||\
    [[ $(dep version | awk 'NR==2{print $3}') != "$DEP_VERSION" ]]; then
    # /usr/local/bin is expected to be on $PATH.
    curl -L \
        -s https://github.com/golang/dep/releases/download/$DEP_VERSION/dep-linux-amd64 \
        -o /usr/local/bin/dep

    chmod +x /usr/local/bin/dep
fi

# Remove the $APP_BUILD_DIR just in case it was left behind in a failed build.
rm -rf $APP_BUILD_DIR

# Setup the application directory
mkdir -p $APP_BUILD_DIR

# mv all files to $APP_BUILD_DIR
# https://superuser.com/questions/62141/how-to-move-all-files-from-current-directory-to-upper-directory
mv * .[^.]* $APP_BUILD_DIR
cd $APP_BUILD_DIR

# Pull in dependencies into vendor/.
dep ensure

# Build the binary with jsoniter tag.
go build -o application -tags=jsoniter .

# Modify permissons to make the binary executable.
chmod +x application
# Move the binary back to staging dir.
# Along with the configuration files.
mkdir $APP_STAGING_DIR/bin
# By default, `bin/application` is executed. This way, a Procfile isn't needed.
mv application $APP_STAGING_DIR/bin
cp -r config $APP_STAGING_DIR
# TODO: Fix the viper not working with env var
# Generate prod config from env variables
/opt/elasticbeanstalk/bin/get-config environment --output YAML | sed s/${ENV_VAR_PREFIX}//g > $APP_STAGING_DIR/config/prod.app.yaml
# Copy .ebextensions back to staging directory.
# cp -r .ebextensions $APP_STAGING_DIR

# Clean up.
rm -rf $APP_BUILD_DIR

echo "Build successful!!"

我的build.sh文件由EBS使用此Buildfile调用：

make: ./build.sh

Etvoilà！现在一切正常了:)）

在elasticbeanstalk上部署私有github repo golang app
