gerritをとりあえず立ち上げて、使うまでの手順 (docker利用)

# memo

# fix the permission error

```
docker ps
permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/json": dial unix /var/run/docker.sock: connect: permission denied

sudo chmod 666 /var/run/docker.sock
```

# pull docker image

https://hub.docker.com/r/gerritcodereview/gerrit

https://hub.docker.com/r/gerritcodereview/gerrit/tags
から使いたいtagをみて

```
docker pull gerritcodereview/gerrit:3.10.1-ubuntu22
```

```
docker run -d -p 8080:8080 -p 29418:29418 gerritcodereview/gerrit
```

# run

```
docker run -ti -p 8080:8080 -p 29418:29418 gerritcodereview/gerrit
```

明示タグでの起動

```
docker run -ti -p 8080:8080 -p 29418:29418 gerritcodereview/gerrit:3.9.6-ubuntu22
```

## dockerの他の操作

### dockerの停止

```
docker stop $(docker ps -q)
```

### docker images (pull済みのimageのlist)

```
docker images
```

### remove images

```
docker rmi c4ba92a033df
```

or

```
docker rmi gerritcodereview/gerrit:latest
```

# access to the gerrit

```
ifconfig | grep 192
```

From another machine (同じマシンならlocalhostでok)

```
open http://themachine.local:8080
```

# add key to gerrit

```
cat ~/.ssh/id_rsa.pub
```

上をブラウザからSettings/SSH Keysに追加

# check from the same machine as the browser

gerritを走らせているマシンをubuntu2とする (.ssh/configに追加しておくと良い)

```~/.ssh/config
Host gerrit
    HostName themachine.local
    User admin
    Port 29418
    Protocol 2
    IdentityFile ~/.ssh/id_rsa
    ServerAliveInterval 60
```

```
ssh gerrit gerrit -h
```

remove the machine ip's fingerprint from ~/.ssh/known_hosts

# create the test

```
ssh gerrit gerrit create-project --empty-commit test
```

# clone

```
cd ~/work/gerrit_temp
git clone ssh://gerrit/test 
cd test
scp -O -p gerrit:hooks/commit-msg .git/hooks/
```

```~/work/gerrit_temp/test/.git/commit-msg
