kong 和 kong的web UI管理界面简单部署

kong的部署方式比较简单,github仓库有all-in-one的资源配置清单:

本地的话由于是mac本,需要将LoadBalance的service类型修改为NodePort才可以访问

kong + konga部署

konga的部署采用docker的方式:

创建pg数据库,这里没有配置数据的永久存储,在正式环境上面应该将数据持久化:

创建kong-net 的网络:

docker create network kong-net
docker run -d --name konga-database  \
                    --network=kong-net  \
                    -p 5433:5432 \
                    -e "POSTGRES_USER=konga"  \
                    -e "POSTGRES_DB=konga" \
                    -e "POSTGRES_PASSWORD=konga"  \
                    postgres:9.6

初始化konga数据库:

➜  ~ docker run --rm  --network=kong-net  \
                       pantsel/konga:latest \
                       -c prepare \
                       -a postgres \
                       -u postgres://konga:[email protected]:5432/konga
debug: Preparing database...
Using postgres DB Adapter.
Database exists. Continue...
debug: Hook:api_health_checks:process() called
debug: Hook:health_checks:process() called
debug: Hook:start-scheduled-snapshots:process() called

debug: User seed planted
debug: Seeding Kongnode...
debug: Kongnode seed planted
debug: Seeding Emailtransport...
debug: Emailtransport seed planted
debug: Database migrations completed!
如上输出后,表示数据库初始化成功

启动konga实例:

docker run -d -p 1337:1337  \
               --network kong-net  \
               -e "DB_ADAPTER=postgres"  \
               -e "DB_URI=postgres://konga:[email protected]:5432/konga"  \
               -e "NODE_ENV=development"  \
               -e "DB_PASSWORD=konga" \
               --name konga \
               pantsel/konga
