摘要: 2016.12.14:ARM64服务器再添神器,Docker for AArch64指日可待。

编译过程

在96Boards 的410C上编译Docker(这里使用Dokcer 1.14 Master版本,方法参考),遇到些问题,解决方法如下:

修改Docker源码目录下的Dockerfile.aarch64文件

  • 修改 FROM aarch64/ubuntu:wily 去掉wily,因为wily版很多源都没法下载。
  • Docker编译需要GOROOT_BOOTSTRAP,在安装包中加入: golang
  • 在docker-py安装前运行:pip install setuptools
  • 需要下载go的源代码安装,访问不了的设置代理,示意:curl -x 192.168.1.11:9999,把这里的地址改成自己的代理服务器。
  • 内存不足,启用虚存支持,参考:https://my.oschina.net/u/2306127/blog/657269
  • 主存储空间不足,把Docker放到U盘或SD卡上,参考:https://my.oschina.net/u/2306127/blog/653569

** 基于ARM64的很多容器资源:https://github.com/multiarch**

运行问题解决

因为不明原因,最后make deb编译失败,但到目录中看,bundles中dockerD和docker都已经生成好了。

  • 拷贝到/usr/bin目录中,修改/lib/systemd/system/docker.service文件。
  • 但systemctl docker start运行时又报container找不到错误。
  • 到 **hack/dockerfile/install-binaries.sh **中找到containerd和runc的相应安装代码,手工运行、安装到/usr/local/bin,建立软连接,docker就可以正常启动了。

注意:

  • 由于最近github.com强制使用了https,导致go get和git clone 原来的http网站失败。
  • 出错显示,网站找不到,参考这里的方法解决。
SSL CA错误的解决:
运行:git config --global http.sslverify false.
或者:env GIT_SSL_NO_VERIFY=true
添加CA:http://askubuntu.com/questions/645818/how-to-install-certificates-for-command-line

安装containerd和runc

export GOPATH="/home/linaro" 

#复制DockerD服务器到系统目录
cp docker1.14.0-dev /usr/bin/
#修改/lib/systemd/system/docker.service中的ExecStart=/usr/bin/dockerd为ExecStart=/usr/bin/docker1.14.0-dev

#以后使用dox来运行新的Docker客户端。
cp  docker1.14.0 /usr/local/bin/dox
 
# Install runc
export RUNC_COMMIT=f59ba3cdd76fdc08c004f42aa915996f6f420899
git clone https://github.com/docker/runc.git "$GOPATH/src/github.com/opencontainers/runc"
cd "$GOPATH/src/github.com/opencontainers/runc"
git checkout -q "$RUNC_COMMIT"
make static BUILDTAGS="seccomp apparmor selinux" 
cp runc /usr/local/bin/docker-runc
ln -s /usr/local/bin/docker-runc /usr/local/bin/runc

# Install containerd
export CONTAINERD_COMMIT=2a5e70cbf65457815ee76b7e5dd2a01292d9eca8
git clone https://github.com/docker/containerd.git "$GOPATH/src/github.com/docker/containerd" 
cd "$GOPATH/src/github.com/docker/containerd"
git checkout -q "$CONTAINERD_COMMIT"
make static
cp bin/containerd /usr/local/bin/docker-containerd
ln -s /usr/local/bin/docker-containerd  /usr/local/bin/containerd

cp bin/containerd-shim /usr/local/bin/docker-containerd-shim
ln -s /usr/local/bin/docker-containerd-shim /usr/local/bin/containerd-shim

cp bin/ctr /usr/local/bin/docker-containerd-ctr
ln -s /usr/local/bin/docker-containerd-ctr /usr/local/bin/containerd-ctr

修改的docker.service文件

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network.target docker.socket
Requires=docker.socket

[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd -H fd://
ExecReload=/bin/kill -s HUP $MAINPID

# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
# Uncomment TasksMax if your systemd version supports it.
# Only systemd 226 and above support this version.
TasksMax=infinity
TimeoutStartSec=0
# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes
# kill only the docker process, not all processes in the cgroup
KillMode=process

[Install]
WantedBy=multi-user.target

修改的Dockerfile.aarch64文件

下面是修改过的Dockerfile.aarch64,查看原始文件

# This file describes the standard way to build Docker on aarch64, using docker
#
# Usage:
#
# # Assemble the full dev environment. This is slow the first time.
# docker build -t docker -f Dockerfile.aarch64 .
#
# # Mount your source in an interactive container for quick testing:
# docker run -v `pwd`:/go/src/github.com/docker/docker --privileged -i -t docker bash
#
# # Run the test suite:
# docker run --privileged docker hack/make.sh test-unit test-integration-cli test-docker-py
#
# Note: AppArmor used to mess with privileged mode, but this is no longer
# the case. Therefore, you don't have to disable it anymore.
