5.docker的疑难杂症
根据官方文档:https://docs.docker.com/install/linux/docker-ce/centos/搭建docker
1.卸载docker旧版本:
sudo yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-selinux \
docker-engine-selinux \
docker-engine\
2.安装相关工具类:
sudo yum install -y yum-utils \
device-mapper-persistent-data \
lvm2
3.配置docker仓库:
sudo yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
会报以下错误:
Loaded plugins: fastestmirror
adding repo from: https://download.docker.com/linux/centos/docker-ce.repo
grabbing file https://download.docker.com/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo
Could not fetch/save url https://download.docker.com/linux/centos/docker-ce.repo to file /etc/yum.repos.d/docker-ce.repo
: [Errno 14] curl#35 - "TCP connection reset by peer
这是由于国内访问不到docker官方镜像的缘故
可以通过aliyun的源来完成:
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
出现以下内容则表示docker仓库配置成功:
Loaded plugins: fastestmirror
adding repo from: http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
grabbing file http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo
repo saved to /etc/yum.repos.d/docker-ce.repo
4.安装docker
sudo yum install docker-ce
出现以下异常:
Loaded plugins: fastestmirror
base
https://download-stage.docker.com/linux/centos/7/x86_64/stable/repodata/repomd.xml: [Errno 14] curl#35 - "TCP connection reset by peer"
Trying other mirror.
One of the configured repositories failed (Docker CE Stable - x86_64),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Run the command with the repository temporarily disabled
yum --disablerepo=docker-ce-stable ...
4. Disable the repository permanently, so yum won't use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use --enablerepo for temporary usage:
yum-config-manager --disable docker-ce-stable
or
subscription-manager repos --disable=docker-ce-stable
5. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=docker-ce-stable.skip_if_unavailable=true
failure: repodata/repomd.xml from docker-ce-stable: [Errno 256] No more mirrors to try.
https://download-stage.docker.com/linux/centos/7/x86_64/stable/repodata/repomd.xml: [Errno 14] curl#35 - "TCP connection reset by peer"
分析原因为:阿里的镜像库文件也指向docker官方库,所以需要修改库文件
sudo vim /etc/yum.repos.d/docker-ce.repo
通过命令把https://download-stage.docker.com替换为http://mirrors.aliyun.com/docker-ce
命令如下:
:%s#https://download-stage.docker.com#http://mirrors.aliyun.com/docker-ce#g
在执行安装docker的部分妈可安装成功。
sudo yum install docker-ce
内容如下:
Installed:
docker-ce.x86_64 0:18.03.0.ce-1.el7.centos
Dependency Installed:
audit-libs-python.x86_64 0:2.7.6-3.el7 checkpolicy.x86_64 0:2.5-4.el7 container-selinux.noarch 2:2.42-1.gitad8f0f7.el7 libcgroup.x86_64 0
libtool-ltdl.x86_64 0:2.4.2-22.el7_3 pigz.x86_64 0:2.3.3-1.el7.centos policycoreutils-python.x86_64 0:2.5-17.1.el7 python-IPy.noarch
Complete!
5.验证docker安装成功:
启动docker:
sudo systemctl start docker
验证docker:
sudo docker run hello-world
则会出现以下异常:
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
9bb5a5d4561a: Pulling fs layer
docker: error pulling image configuration: Get https://dseasb33srnrn.cloudfront.net/registry-v2/docker/registry/v2/blobs/sha256/e3/e38bc07ac18e
See 'docker run --help'.
此错误也是网络问题:国内无法访问dockerhub
配置阿里云的docker镜像库:在阿里云开通容器镜像服务拿到加速地址在执行以下命令:
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://{自已的编码}.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
再次验证docker:
sudo docker run hello-world
出现以下内容则表示安装成功:
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
9bb5a5d4561a: Pull complete
Digest: sha256:f5233545e43561214ca4891fd1157e1c3c563316ed8e237750d59bde73361e77
Status: Downloaded newer image for hello-world:latest
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
