我想在我们的CI工具CircleCI中尝试让Rails和MSSQL交谈。我在Mac上工作，所以设置它是相当痛苦的。我使用Homebrew在本地安装了FreeTDS。然后我产生了一个MSSQL docker镜像，并在我的rails应用程序中设置我的配置指向它，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
password: P@55w0rd
test:
<<: *default
host: localhost
database: collections_test
username: sa
password: P@55w0rd
我用：
构建了一个泊坞窗图像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
此图片托管于docker hub here。
接下来我构建了CircleCI配置：
version: 2
jobs:
build:
working_directory: ~/collections-api
docker:
- image: legendaryrob/ruby:2.4.1-node-browser-freetds54-lib6c
environment:
RAILS_ENV: test
- image: microsoft/mssql-server-linux
environment:
ACCEPT_EULA: Y
SA_PASSWORD: P@55w0rd
environment:
RAILS_ENV: test
steps:
- checkout
- restore_cache:
name: Restore bundle cache
keys:
- collections-api-bundle-{{ checksum "Gemfile.lock" }}
- run:
name: Allow CI to read from pdg gemserver
command: bundle config https://gems.pdg.io/ $GEMS_USERNAME:$GEMS_PASSWORD
- run:
name: Bundle Install
command: bundle install --path vendor/bundle --jobs 4 --retry 3
- save_cache:
name: Store bundle cache
key: collections-api-bundle-{{ checksum "Gemfile.lock" }}
paths:
- vendor/bundle
- run:
name: Wait for DB
command: dockerize -wait tcp://localhost:1433 -timeout 1m
- run:
name: test tds connection
command: tsql -C
# Run setup
- run: ./spec/setup/circle_setup.sh
- run:
name: Create the database
command: bundle exec rake -v --trace db:create
- run:
name: Migrate the database
command: bundle exec rake -v --trace db:migrate
- run:
name: Check environment variables are present
command: bundle exec rake env_variables:check
- run:
name: Run tests
command: bundle exec rspec
我直接从Microsoft的docker hub帐户获取的MSSQL docker镜像 - ＆gt; https://hub.docker.com/r/microsoft/mssql-server-linux/
在这里你可以看到几件事。我设置了我用TDS安装的ruby盒子以及所需的所有依赖项。我确保我们使用的是我们在本地使用的相同版本的TDS，因为它在本地工作，我还尝试了一些其他版本，只是因为我正在处理一个flakey版本。
我还确保我们可以连接到MSSQL docker box并确保我们有正确的tds配置：
- run:
name: Wait for DB
command: dockerize -wait tcp://localhost:1433 -timeout 1m
- run:
name: test tds connection
command: tsql -C
这将产生以下结果：
#!/bin/bash -eo pipefail
dockerize -wait tcp://localhost:1433 -timeout 1m

然后我得到超时。这些超时是间歇性的，当我们尝试连接到localhost时会出现这些超时：1433
但主要是当我们进入佣金任务时。
下面是我得到的堆栈跟踪，我已经尝试了几个不同版本的MSSQL docker，但没有效果。如果有人试过这样做，请告诉我，我真的很感激这方面的一些帮助。

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，我们有另一个团队依赖于使用MSSQL的Access。我只是希望有一个人在那里与这个野兽战斗并赢得了胜利。
