If you want to contribute to swarm, then build swarm by yourself is required.
Prerequisites:
Install golang.
Note: beginning with Swarm 0.4 golang 1.4.x or later is required for building Swarm.
Install Git.
Install godep
Build step:
Run following commands to check the required softwares have been installed well on your machine:
# git version git version 1.9.1 # go version go version go1.5.2 linux/amd64 # godep version godep v37 (linux/amd64/go1.5.2)
Set GOPATH, download swarm source code and it‘s all dependencies:
# export GOPATH=/opt/go # godep get github.com/docker/swarm
Note: If some packages can not be downloaded due to the network issue, you can configure the network proxy to download them manually, and copy them to $GOPATH/src, for example:
# godep get github.com/docker/swarm package golang.org/x/net/context: unrecognized import path "golang.org/x/net/context" godep: exit status 1
Address this issue: configure network proxy to download "golang.org/x/net/context" and copy downloaded files to /opt/go/src/golang.org/x/net/context
Note: swich to the corresponding docker branch that the current developing swarm is required:
# godep get github.com/docker/swarm package github.com/docker/docker/pkg/parsers/filters: cannot find package "github.com/docker/docker/pkg/parsers/filters" in any of: /usr/local/go/src/github.com/docker/docker/pkg/parsers/filters (from $GOROOT) /opt/go/src/github.com/docker/docker/pkg/parsers/filters (from $GOPATH) godep: exit status 1
Address this issue:
# cd /opt/go/src/github.com/docker/docker # git branch * master # git checkout release/v1.9
Run godep again to check whether all dependencies are downloaded:
# godep get github.com/docker/swarm
Then you can find the swam binary are located in your GOPATH
# ll /opt/go/bin/swarm -rwxr-xr-x 1 root root 22577112 Dec 16 15:38 /opt/go/bin/swarm*
Rebuild the swarm binary manually after your change the swam code:
Note: the swam source code also has be downloaded and located in your GOPATH:
# cd /opt/go/src/github.com/docker/swarm/ # git branch * master # git remote -v origin https://github.com/docker/swarm (fetch) origin https://github.com/docker/swarm (push) # git checkout -b forYourChanges -- Do your changes # rm -rf /opt/go/bin/swarm # go build # go install # ll /opt/go/bin/swarm -rwxr-xr-x 1 root root 24180448 Dec 16 16:02 /opt/go/bin/swarm*
The above steps have be verified on Utuntu 14.04.
