docker chainlink 容器未连接到 postgres 数据库

【问题描述】：

我想在本地 ubuntu 机器上运行 chainlink 节点。 我使用以下命令安装 postgresql：

sudo apt install postgresql

调整防火墙设置：

sudo ufw allow from any to any port 5432 proto tcp

访问 postgresql.conf 文件：

sudo gedit /etc/postgresql/12/main/postgresql.conf

修改文件

listen_addresses = ‘*’

sudo gedit /etc/postgresql/14/main/pg_hba.conf

修改文件

host all all 172.17.0.0/16     md5

创建的用户和数据库见下图： [![这张图片显示了我在 postgresql 中的数据库和用户][1]][1]

我的 .env 文件的配置是：

ROOT=/chainlink
LOG_LEVEL=debug
ETH_CHAIN_ID=42
MIN_OUTGOING_CONFIRMATIONS=2
LINK_CONTRACT_ADDRESS=0xa36085F69e2889c224210F603D836748e7dC0088
CHAINLINK_TLS_PORT=0
SECURE_COOKIES=false
GAS_UPDATER_ENABLED=true
ALLOW_ORIGINS=*
ETH_URL=wss://kovan.infura.io/ws/v3/f0d1d3d2fbb649e29922ec37d4ff0b45
DATABASE_URL=postgresql://chainlink:password#123@127.0.0.1:5432/chainlink?ssl=disable
DATABASE_TIMEOUT=0

我在终端中运行以下命令，镜像版本为 0.10.14。

cd ~/.chainlink-kovan && docker run -p 6688:6688 --name chainlink-node --add- 
host=host:127.0.0.1 -v ~/.chainlink-kovan:/chainlink -it --env-file=.env 
smartcontract/chainlink:0.10.14 local n

它没有连接到 postgresql 数据库。有时它会显示 .env 文件中的 DATABASE_URL 行错误。 当前错误日志是：

    {"level":"warn","ts":1634243680.5286717,"caller":"logger/default.go:134","msg":"GAS_UPDATER_ENABLED has been deprecated, to enable the block history estimator, please use GAS_ESTIMATOR_MODE=BlockHistory instead"}

    【解决方案1】：

    问题出在 DATABASE_URL 变量中。 我在我的数据库密码中使用了 # 字符。我删除了#，现在问题解决了。
