Rails MSSQL - TinyTds::错误：Adaptive Server 连接超时

leg*_*rob 5 sql-server ruby-on-rails freetds docker circleci

我想尝试让 Rails 和 MSSQL 在我们的 CI 工具 CircleCI 中进行对话。我在 Mac 上工作，所以设置起来相当轻松。我使用 Homebrew 在本地安装了 FreeTDS。然后我生成了一个 MSSQL docker 映像，并在 Rails 应用程序中设置我的配置以指向它，一切正常。

CircleCI 有点不同。

我做了以下事情。

在我的 gemfile 中添加：

# mssql database gems
gem 'tiny_tds'
gem 'activerecord-sqlserver-adapter'

修改了我们的database.yml文件：

default: &default
  adapter: sqlserver
  pool: 5
  encoding: utf8
  mode: dblib

development:
  <<: *default
  host: localhost
  database: collections_development
  username: sa

test:
  <<: *default
  host: localhost
  database: collections_test

我用以下命令构建了一个 docker 镜像：

FROM circleci/ruby:2.4.1-node-browsers

RUN set -ex \
  && sudo apt-get install build-essential \
  && sudo apt-get install libc6-dev \
  && sudo wget -O freetds-1.00.54.tar.gz "ftp://ftp.freetds.org/pub/freetds/stable/freetds-1.00.54.tar.gz" \
  && sudo tar -xzvf freetds-1.00.54.tar.gz \
  && cd freetds-1.00.54 \
  && sudo ./configure \
  && sudo make \
  && sudo make install

该镜像托管在 docker hub上。

接下来我构建了 CircleCI 配置：

我直接从 Microsoft 的 docker hub 帐户获取的 MSSQL docker 映像 -> https://hub.docker.com/r/microsoft/mssql-server-linux/

在这里你可以看到一些事情。我设置了我构建的 ruby​​ box，安装了 TDS 以及所需的所有依赖项。我确保我们使用与本地使用的 TDS 版本相同的版本，因为它在本地工作，我还尝试了一些其他版本，以防万一我正在处理不稳定的版本。

我还确保我们可以连接到 MSSQL docker 框并确保我们拥有正确的 tds 配置：

- run:
    name: Wait for DB
    command: dockerize -wait tcp://localhost:1433 -timeout 1m

- run:
    name: test tds connection
    command: tsql -C

但后来我超时了。这些超时是间歇性的，当我们尝试连接到 localhost:1433 时有时会发生

但大多数情况下，它发生在我们执行 rake 任务时。

下面是我得到的堆栈跟踪，我也尝试了几个不同版本的 MSSQL docker，但没有效果。如果有人尝试过这样做，请告诉我，我非常感谢为此提供一些帮助。

注意：我们需要连接到 MSSQL 的原因是因为我们将在短时间内写入数据库，我们有另一个依赖使用 MSSQL 的 Access 的团队。我只是希望还有其他人能够与这只野兽战斗并获胜。
