使用 edeliver 和 distillery 构建升级版本答案

【问题标题】：Build upgrade release with edeliver and distillery使用 edeliver 和 distillery 构建升级版本

【问题描述】：

版本：（构建和生产系统都相同）

灵药：1.4.0

操作系统：Ubuntu 14.04 LTS

酒厂配置：

use Mix.Releases.Config,
    default_release: :default,
    default_environment: :prod

environment :dev do
  set dev_mode: true
  set include_erts: false
  set cookie: :"cookie"
end

environment :prod do
  set include_erts: true
  set include_src: false
  set cookie: :"cookie"
end

release :my_app do
  set version: current_version(:my_app)
end

交付配置：

APP="my_app"

AUTO_VERSION=git-revision+build-date

BUILD_HOST="my_build_host"
BUILD_USER="deployer"
BUILD_AT="/tmp/my_app"

PRODUCTION_HOSTS="same_as_build_host"
PRODUCTION_USER="deployer"
DELIVER_TO="/home/my_app"

# For *Phoenix* projects, symlink prod.secret.exs to our tmp source
pre_erlang_get_and_update_deps() {
  local _prod_secret_path="/home/xxx/config/prod.secret.exs"
  if [ "$TARGET_MIX_ENV" = "prod" ]; then
    __sync_remote "
      ln -sfn '$_prod_secret_path' '$BUILD_AT/config/prod.secret.exs'
    "
  fi
}

我的初始版本通过mix edeliver update production --branch=development --start-deploy 成功，并且应用程序运行良好。当我尝试热代码重新加载时，

mix edeliver build upgrade --branch=development

命令失败

build command requires --from= or --with argument.

当有AUTO_VERSION 或者我错过了任何配置时，edeliver 不应该处理这个吗？

另外，执行命令mix edeliver upgrade production --branch=development --verbose，会报错

==> Upgrade from 0.0.1+297b4ff-20170221 to 0.0.1+f9ffa04-20170222 failed:

==> Failed to build release:
    :bad_upgrade_spec

A remote command failed on:

  deployer@my_host

Output of the command is shown above and the command executed
on that host is printed below for debugging purposes:

    cd /tmp/jn
    if [ "mix" = "rebar" ]; then
      echo "using rebar to generate release"
      ./rebar   -f generate
    elif [ "mix" = "relx" ]; then
      echo "using relx to generate release"
      ./relx release
    elif [ "mix" = "mix" ]; then
      echo "using mix to generate release"
      MIX_ENV="prod" LINK_SYS_CONFIG="" LINK_VM_ARGS="" APP="jn" AUTO_VERSION="git-revision+build-date" BRANCH="development" SKIP_RELUP_MODIFICATIONS="" RELUP_MODIFICATION_MODULE="" USING_DISTILLERY="true" mix do release.version  --verbose,  release --verbose --env="prod" --name="jn" --upgrade --upfrom="0.0.1+297b4ff-20170221"
    fi

【解决方案1】：

mix edeliver upgrade production --branch=development --verbose 上的错误看起来您的版本存储中没有以前的版本。

您可以尝试再次构建该版本，将其部署到您的服务器并尝试升级。

希望有帮助:)

【讨论】：

我的旧版本位于 my_project_root/.deliver/releases 下。但它并没有试图找到那个。相反，它尝试在 _build/prod/rel/ 获取

【解决方案2】：

我前段时间进入了这个，但我无法让它开箱即用。我最终自己完成了副本（符号链接）：

.deliver/config

# Fix
# ==> Upgrade from 0.0.3+71-7a01b46 to 0.0.4+87-6c98597 failed:
#  0.0.3+71-7a01b46 does not exist at _build/prod/rel/...
pre_erlang_generate_release() {
  if [ "$TARGET_MIX_ENV" = "prod" ]; then
    __sync_remote "
      ln -sfn '$REL_DIR' '$BUILD_AT/_build/prod/'
    "
  fi
}

这个钩子在构建发布之后，在erlang生成升级之前执行。

哎呀。该问题与https://github.com/boldpoker/edeliver/issues/182 有关。
