docker部署postgres

docker run -d --name kong-postgres -e POSTGRES_PASSWORD=kong -e PGDATA=/var/lib/postgresql/data/pgdata -p 5432:5432 postgres:9

在postgres中创建kong、konga数据库

su postgres

psql

create user kong;

create database kong owner kong;

create user konga;

alter user kong with encrypted password 'kongpassword';

grant all privileges on database kong to kong;

grant all privileges on database konga to kong;
对PGSQL数据库初始化

#脚本跑完容器就关闭了
docker run -it --rm -e "KONG_DATABASE=postgres" -e "KONG_PG_HOST=192.167.0.12" -e "KONG_PG_PORT=5432" -e "KONG_PG_USER=kong" -e "KONG_PG_PASSWORD=kong" -e "KONG_PG_DATABASE=kong" -e "KONG_CASSANDRA_CONTACT_POINTS=kong" kong:latest kong migrations bootstrap
初始化konga数据库

#脚本跑完容器就关闭了
docker run --rm pantsel/konga -c prepare -a postgres -u postgresql://kong:kong@192.168.2.143:5432/konga
部署kong网关

修改postgres数据库地址，账号密码
