cephadm 离线方式配置

导出podman镜像

需要把这些镜像导出来，做成离线包

[root@ceph1 ~]# podman save -o ceph.tar quay.io/ceph/ceph:v15

[root@ceph1 ~]# ls

anaconda-ks.cfg ceph.tar     

[root@ceph1 ~]# du -sh ceph.tar

1.2G        ceph.tar

[root@ceph1 ~]# podman save -o prometheus.tar quay.io/prometheus/prometheus:v2.18.1

[root@ceph1 ~]# podman save -o ceph-grafana.tar quay.io/ceph/ceph-grafana:6.7.4

[root@ceph1 ~]# podman save -o node-exporter.tar quay.io/prometheus/node-exporter:v0.18.1

[root@ceph1 ~]# podman save -o alertmanager.tar quay.io/prometheus/alertmanager:v0.20.0

修改cephadm脚本

最后需要修改的是cephadm安装脚本，默认安装的时候cephadm是去网上pull镜像，但是实际生产环境是没有外网的，需要修改成直接用本地的镜像

修改_pull_image函数的cmd列表中的pull，将其修改为images。(我用的是octopus版本，其他版本基本不变)

@default_image

def command_pull():

    # type: () -> int

" v" a; o# _2 e( ~# O" A+ w) _

    _pull_image(args.image)

    return command_inspect_image()

% x3 \- w  F" |, p0 x" q7 Z

def _pull_image(image):

    # type: (str) -> None

    logger.info('Pulling container image %s...' % image)

    ignorelist = [

        "error creating read-write layer with ID",

        "net/http: TLS handshake timeout",

        "Digest did not match, expected",

8 p2 E$ |+ H' u+ B

  #//  cmd = [container_path, 'pull', image]

   cmd = [container_path, 'images', image]

    cmd_str = ' '.join(cmd)

4 O, w0 V4 R+ m: Z  ?

    for sleep_secs in [1, 4, 25]:

        out, err, ret = call(cmd)

        if not ret:

            return

7 Y, U+ E- a1 H/ a( x

        if not any(pattern in err for pattern in ignorelist):

            raise RuntimeError('Failed command: %s' % cmd_str)

        logger.info('"%s failed transiently. Retrying. waiting %s seconds...' % (cmd_str, sleep_secs))

        time.sleep(sleep_secs)

8 J/ c0 o& R6 Z9 k% E/ I# x9 o

    raise RuntimeError('Failed command: %s: maximum retries reached' % cmd_str)
