helm [helm] v.掌(舵)；掌握；给…戴上头盔

ins

轻松完爆Helm私有仓库 

wget -c https://get.helm.sh/helm-v3.9.3-linux-amd64.tar.gz
tar xvf helm-v3.9.3-linux-amd64.tar.gz
sudo mv linux-amd64/helm /usr/local/bin/helm

 wget -c https://get.helm.sh/helm-v3.0.3-linux-amd64.tar.gz
    tar xvf  helm-v3.0.3-linux-amd64.tar.gz 
     sudo mv linux-amd64/helm /usr/local/bin/helm


果想要更舒服一些，那么可以添加自动完成的代码：

# source <(helm completion bash)

添加 Chart 仓库

在 Helm 3.0 版本中，默认是不会添加 Chart 仓库，所以这里我们需要手动添加，下面是添加一些常用的 Charts 库，命令如下：

$ helm repo add  elastic    https://helm.elastic.co
$ helm repo add  gitlab     https://charts.gitlab.io
$ helm repo add  harbor     https://helm.goharbor.io
$ helm repo add  bitnami    https://charts.bitnami.com/bitnami
$ helm repo add  incubator  https://kubernetes-charts-incubator.storage.googleapis.com
$ helm repo add  stable     https://kubernetes-charts.storage.googleapis.com

增加完仓库后，需要执行更新命令，将仓库中的信息进行同步：

$ helm repo update

    注意：如果有的仓库不能正常解析，请更换 DNS 地址，在测试过程中，发现有的能正常解析，有的不能。如果还不行，就直接将域名和对应的地址写死在 Host 文件中

Helm 的基本操作

安装应用

通过 Helm 在 Repo 中查询可安装的 nginx 

helm search repo nginx

kubectl get secret --namespace "mynamespace" redis-cluster -o jsonpath="{.data.redis-password}" | base64 -d
 1301  export REDIS_PASSWORD=$(kubectl get secret --namespace "mynamespace" redis-cluster -o jsonpath="{.data.redis-password}" | base64 -d)

ins mysql

参考官方 https://helm.sh/docs/intro/quickstart/ 

 helm repo add stable https://kubernetes-charts.storage.googleapis.com/

$ helm repo update              # Make sure we get the latest list of charts

$ helm install stable/mysql --generate-name

NAME: mysql-1583911857
LAST DEPLOYED: Wed Mar 11 15:31:01 2020
NAMESPACE: default
STATUS: deployed
REVISION: 1
NOTES:
MySQL can be accessed via port 3306 on the following DNS name from within your cluster:
mysql-1583911857.default.svc.cluster.local

To get your root password run:

    MYSQL_ROOT_PASSWORD=$(kubectl get secret --namespace default mysql-1583911857 -o jsonpath="{.data.mysql-root-password}" | base64 --decode; echo)

To connect to your database:

1. Run an Ubuntu pod that you can use as a client:

    kubectl run -i --tty ubuntu --image=ubuntu:16.04 --restart=Never -- bash -il

2. Install the mysql client:

    $ apt-get update && apt-get install mysql-client -y

3. Connect using the mysql cli, then provide your password:
    $ mysql -h mysql-1583911857 -p

To connect to your database directly from outside the K8s cluster:
    MYSQL_HOST=127.0.0.1
    MYSQL_PORT=3306

    # Execute the following command to route the connection:
    kubectl port-forward svc/mysql-1583911857 3306

    mysql -h ${MYSQL_HOST} -P${MYSQL_PORT} -u root -p${MYSQL_ROOT_PASSWORD}
