我正在努力让 Pact Broker 在 docker 容器中运行以连接到我在 Windows 上安装的本地 PostgreSQL。

这就是我的 docker run 命令的样子...

docker run pactfoundation/pact-broker 
-e PACT_BROKER_DATABASE_USERNAME=pact_broker 
-e PACT_BROKER_DATABASE_PASSWORD={Password} 
-e PACT_BROKER_DATABASE_HOST=host.docker.internal 
-e PACT_BROKER_DATABASE_NAME=pact_broker 
-e PACT_BROKER_DATABASE_PORT=5432 
-p 9292:9292

返回以下错误...

Unable to load application: Sequel::DatabaseConnectionError: PG::ConnectionBad: could not connect to server: No such file or directory
        Is the server running locally and accepting
        connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
bundler: failed to load command: puma (/pact_broker/vendor/bundle/ruby/2.6.0/bin/puma)
Sequel::DatabaseConnectionError: PG::ConnectionBad: could not connect to server: No such file or directory
        Is the server running locally and accepting
        connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

这是我在 pgAdmin 4 中的数据库和用户

这是我用来测试连接的命令

psql postgresql://pact_broker:{Password}@localhost/pact_broker

它返回以下...

psql (13.3)
WARNING: Console code page (65001) differs from Windows code page (1252)
         8-bit characters might not work correctly. See psql reference
         page "Notes for Windows users" for details.
Type "help" for help.

我也尝试过运行以下返回相同错误的命令

docker run pactfoundation/pact-broker -e PACT_BROKER_DATABASE_URL=postgresql://pact_broker:{Password}@host.docker.internal/pact_broker -p 9292:9292

我的postgres.conf文件包含listen_addresses = '*'并且我pg_hba.conf的包含以下内容

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     scram-sha-256
# IPv4 local connections:
host    all             all             127.0.0.1/32            scram-sha-256
# IPv6 local connections:
host    all             all             ::1/128                 scram-sha-256
# Allow replication connections from localhost, by a user with the
# replication privilege.
local   replication     all                                     scram-sha-256
host    all             all             0.0.0.0/0               trust
host    replication     all             ::1/128                 scram-sha-256
host    all             all             ::/0                    md5

我在使用 Azure Database for PostgreSQL 托管的实例时遇到了类似问题

我的连接字符串如下所示...

psql "host=pactbrokerserver.postgres.database.azure.com port=5432 dbname={your_database} user=postgres@pactbrokerserver password={your_password} sslmode=require"

我试图通过本地协议代理连接到...

docker run pactfoundation/pact-broker 
-e PACT_BROKER_DATABASE_USERNAME=postgres@pactbrokerserver 
-e PACT_BROKER_DATABASE_PASSWORD={Password} 
-e PACT_BROKER_DATABASE_HOST=pactbrokerserver.postgres.database.azure.com 
-e PACT_BROKER_DATABASE_NAME=pactbroker 
-e PACT_BROKER_DATABASE_PORT=5432 
-e PACT_BROKER_DATABASE_CONNECT_MAX_RETRIES=5 
-p 9292:9292

它返回完全相同的错误。

这里可能有什么问题？

我认为这里发生的事情是您已将容器名称放在命令的环境参数列表之前docker run。

因此，PACT_BROKER_DATABASE_NAME与其使用您的自定义值为正在运行的容器设置环境变量和其他环境变量，它们只是被运行时丢弃。

试试这个：

docker run -e PACT_BROKER_DATABASE_USERNAME=pact_broker \
-e PACT_BROKER_DATABASE_PASSWORD={Password} \
-e PACT_BROKER_DATABASE_HOST=host.docker.internal \
-e PACT_BROKER_DATABASE_NAME=pact_broker \
-e PACT_BROKER_DATABASE_PORT=5432 \
-p 9292:9292 \
pactfoundation/pact-broker

调试选项

万一我错了，问题似乎可能与网络路径有关。为了排除这种情况，我们可以通过将入口点（通常是启动和运行 Web 服务器的脚本）替换为 docker 容器中的 shell /bin/sh：

docker run -it --entrypoint /bin/sh --user root -e PACT_BROKER_DATABASE_USERNAME=pact_broker -e PACT_BROKER_DATABASE_PASSWORD=Penwater858 -e PACT_BROKER_DATABASE_HOST=host.docker.internal -e PACT_BROKER_DATABASE_NAME=pact_broker -e PACT_BROKER_DATABASE_PORT=5432 -p 9292:9292 pactfoundation/pact-broker
# once in the container...
apk update
apk add busybox-extras
# see if there is a network path
telnet $PACT_BROKER_DATABASE_HOST $PACT_BROKER_DATABASE_PORT
