Hello, Trying to set up a local configuration of Gogs and Drone, I am finding it difficult to make Drone fetch and clone Gogs repos during the default build procedure. I’d like to underline that _all local_ means that the host is expected to be running without any external net connection; it will be an ‘isolated’ box with all the required docker images downloaded already. However, at now, it is connected, so that I can try different approaches. I believe that this use case is slightly different from [281](http://discourse.drone.io/t/couldnt-resolve-host-on-clone/281): > [@Couldn't resolve host on clone](http://discourse.drone.io/t/couldnt-resolve-host-on-clone/281/4): > > I do have full DNS support for my Gogs endpoint, though, so I’m not playing any tricks with local custom names or docker networking tricks. The main difference being that I do not have any explicit DNS services. I am not playing any tricks neither, but I do rely on local names and docker networking resources. * * * At this initial point, I don’t mind about security (_if you have physical access, you own the machine_). I want just a minimal proof of concept. So, following [1] and [2], this is the `docker-compose.yml` I am using to bootstrap the services (where `DRONE_HOST=drone-server:8000`): [1] [readme.drone.io/admin/installation-guide](http://readme.drone.io/admin/installation-guide) [2] [readme.drone.io/admin/setup-gogs](http://readme.drone.io/admin/setup-gogs) ```auto version: '2' services: gogs: image: gogs/gogs:latest ports: - "127.0.0.1:3000:3000" - "127.0.0.1:10022:22" volumes: [./data:/data] drone-server: depends_on: [gogs] image: drone/drone:latest restart: always ports: ["127.0.0.1:80:8000"] volumes: [./drone:/var/lib/drone] environment: - DRONE_OPEN=false - DRONE_HOST=${DRONE_HOST} - DRONE_GOGS=true - DRONE_GOGS_URL=http://gogs:3000 - DRONE_SECRET=${DRONE_SECRET} drone-agent: depends_on: [drone-server] image: drone/drone:latest command: agent restart: always volumes: [/var/run/docker.sock:/var/run/docker.sock] environment: - DRONE_SERVER=ws://drone-server:8000/ws/broker - DRONE_SECRET=${DRONE_SECRET} ``` Note that `drone-server` depends on `gogs` in order to have IPs assigned in a _known_ order. This is the directory structure: - tmpci/ - data/ - docker/ - docker-compose.yml After launching, `docker-compose up` I check the following info through portainer: ```auto Containers State Name Image IP Address Published ports running tmpci_drone-agent_1 drone/drone:latest 172.18.0.4 - running tmpci_drone-server_1 drone/drone:latest 172.18.0.3 80:8000 running tmpci_gogs_1 gogs/gogs:latest 172.18.0.2 10022:22 3000:3000 running portainer portainer/portainer 172.17.0.2 9000:9000 ``` ```auto Networks Name Id Scope Driver IPAM Driver IPAM Subnet IPAM Gateway none 8a0cf... local null default - - host ad840... local host default - - bridge 14de5... local bridge default 172.17.0.0/16 172.17.0.1 tmpci_default b5fc7... local bridge default 172.18.0.0/16 172.18.0.1 ``` Then, I can reach Gogs from a browser running on the host, through either `localhost:3000` or `172.18.0.2:3000`. Since this is the first run, I configure it. The configuration file is saved to `data/gogs/conf/app.ini`: ```auto APP_NAME = Gogs RUN_USER = git RUN_MODE = prod [database] DB_TYPE = sqlite3 HOST = 127.0.0.1:3306 NAME = gogs USER = root PASSWD = SSL_MODE = disable PATH = data/gogs.db [repository] ROOT = /data/git/gogs-repos [server] DOMAIN = localhost HTTP_PORT = 3000 ROOT_URL = http://172.18.0.2:3000 DISABLE_SSH = false SSH_PORT = 22 START_SSH_SERVER = false OFFLINE_MODE = false [mailer] ENABLED = false [service] REGISTER_EMAIL_CONFIRM = false ENABLE_NOTIFY_MAIL = false DISABLE_REGISTRATION = true ENABLE_CAPTCHA = false REQUIRE_SIGNIN_VIEW = false [picture] DISABLE_GRAVATAR = true ENABLE_FEDERATED_AVATAR = false [session] PROVIDER = file [log] MODE = file LEVEL = Info ROOT_PATH = /app/gogs/log [security] INSTALL_LOCK = true SECRET_KEY = ``` Now, I create a repo through the Gogs frontend, which I can `clone` in the host with either `https://localhost:3000//.git` or `https://localhost:3000//.git`. Then I log in to the Drone frontend through `http://localhost` (with the same user and password created in Gogs), I check that the repo is shown in the list, and I activate it. This results in a webhook with the following payload URL being created in the Gogs repo: `http://drone-server:8000/hook?access_token=eyJhb...`. When the hook is triggered, it works as expected. This is the request: ```auto Headers Request URL: http://drone-server:8000/hook?access_token=eyJhb... Request method: POST Content-Type: application/json X-Gogs-Delivery: eae5a... X-Gogs-Event: push X-Gogs-Signature: 11c24...

However, the build container is unable to access the gogs service. This is the build log: ```auto + git init Initialized empty Git repository in /drone/src/172.18.0.2:3000///compare/6ae1c32c765f5467f4068f6d1922cea35af19411...a30be5fbd153bec305e95f305a65fcaf8f35dce6/.git/ + git remote add origin http://172.18.0.2:3000//.git + git fetch --no-tags origin +refs/heads/master: fatal: unable to access 'http://172.18.0.2:3000//.git/': Failed to connect to 172.18.0.2 port 3000: Operation timed out exit status 128 ``` I tried changing `ROOT_URL=http://172.18.0.2:3000` to `ROOT_URL=http://gogs:3000` in the Gogs configuration, i.e., removed everything and started again with that modification. But I get the same result. This is the `.drone.yml` file in the repo that is being built: ```auto pipeline: build: image: python commands: - python hello.py networks: default: driver: bridge ``` While the build is running, portainer shows that a new subnet is created and the build container is connected to it: ```auto running 0_349414548106078995_clone plugins/git:latest 172.19.0.2 - ``` ```auto 0_2058417003406259118_default a940b... local bridge default 172.19.0.0/16 172.19.0.1 ``` As a possible solution, according to [#1268], I tried replacing the `networks` part with: [#1268] [github.com/drone/drone/issues/1268](http://github.com/drone/drone/issues/1268) ```auto networks: tmpci_default: driver: bridge ``` The result is still the same. For completeness, this is the info of the host: ```auto Version 17.05.0-ce API version 1.29 Go version go1.8.1 OS type linux OS Arch Linux Architecture amd64 Kernel version 4.11.2-1-ARCH ``` Note that, compared to latest replies to [281](http://discourse.drone.io/t/couldnt-resolve-host-on-clone/281/), I am not relying on hostname resolution for the `git fetch` step. I’d like to do so, and I have tried it, but I think it won’t work if hardcoding the IP is not working. I’d be very grateful if anyone with some experience could spot any _evident_ configuration error I might have commited. At the same time, I’d like to know if it is possible to deploy such a set up, in which no reverse proxy is involved. Then, should I read more about networking or is this a possible bug related to this tip? [quote=“JaredReisinger, post:16, topic:281, full:true”]In the `inspect` details, the “drone\_default” shows: ```json {"IPAM": { "Options": null }} ``` … but “foo” has: ```json {"IPAM": { "Options": {} }} ``` [/quote] ---

For completeness, the following configuration uses two subnets: NET\_CI (for drone-server, drone-agent and gogs) and NET\_BUILD (for gogs and build containers): ```auto version: '2' services: gogs: container_name: gogs-srv image: gogs/gogs:latest ports: ["127.0.0.1:3000:3000"] volumes: ["./data_gogs:/data"] drone-server: depends_on: [gogs] image: drone/drone:latest restart: always ports: ["127.0.0.1:80:8000"] volumes: ["./data_drone:/var/lib/drone"] environment: - DRONE_OPEN=true - DRONE_HOST=${DRONE_HOST} - DRONE_GOGS=true - DRONE_GOGS_URL=http://gogs:3000 - DRONE_SECRET=${DRONE_SECRET} - DRONE_NETWORK=${NET_BUILD} drone-agent: depends_on: [drone-server] image: drone/drone:latest command: agent restart: always volumes: ["/var/run/docker.sock:/var/run/docker.sock"] environment: - DRONE_SERVER=ws://drone-server:8000/ws/broker - DRONE_SECRET=${DRONE_SECRET} networks: default: external: name: ${NET_CI} ``` ```auto APP_NAME = app-gogs RUN_USER = git RUN_MODE = prod [database] DB_TYPE = sqlite3 HOST = 127.0.0.1:3306 NAME = gogs USER = root PASSWD = SSL_MODE = disable PATH = data/gogs.db [repository] ROOT = /data/git/gogs-repositories [server] DOMAIN = http://gogs-srv:3000 HTTP_PORT = 3000 ROOT_URL = http://gogs-srv:3000/ DISABLE_SSH = false SSH_PORT = 22 START_SSH_SERVER = false OFFLINE_MODE = false [mailer] ENABLED = false [service] REGISTER_EMAIL_CONFIRM = false ENABLE_NOTIFY_MAIL = false DISABLE_REGISTRATION = true ENABLE_CAPTCHA = false REQUIRE_SIGNIN_VIEW = false [picture] DISABLE_GRAVATAR = true ENABLE_FEDERATED_AVATAR = false [session] PROVIDER = file [log] MODE = file LEVEL = Info ROOT_PATH = /app/gogs/log [security] INSTALL_LOCK = true SECRET_KEY = ``` This is the start procedure: ```auto # docker network create ${NET_CI} # docker network create ${NET_BUILD} # docker-compose up # docker network connect ${NET_BUILD} gogs-srv ``` An this the cleaning procedure: ```auto # docker-compose rm # docker network prune ```
