Docker certificate has expired or is not yet valid - docker

Question

I just installed docker for the first time and when the default virtualbox or 'docker-machine'(not sure what it is called I run into this error:
This is an excerpt
Checking connection to Docker...
Error creating machine: Error checking the host: Error checking and/or regenerat
ing the certs: There was an error validating certificates for host "192.168.99.1
01:2376": x509: certificate has expired or is not yet valid
You can attempt to regenerate them using 'docker-machine regenerate-certs [name]
'.
Be advised that this will trigger a Docker daemon restart which might stop runni
ng containers.
I tried using the docker-machine regenerate-certs [name] command and it seemed to work no errors were raised at least. Only when I attempted to run docker's hello world command this is the result I got.
docker: error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.39/c
ontainers/create: open //./pipe/docker_engine: The system cannot find the file s
pecified. In the default daemon configuration on Windows, the docker client must
be run elevated to connect. This error may also indicate that the docker daemon
is not running.
See 'docker run --help'.
I searched up similar errors and found a few case where creating a new virtualbox/docker-machine(still don't know what its called) solved it but the same error that appeared with the default box showed up.
Error creating machine: Error checking the host: Error checking and/or regenerat

01:2376": x509: certificate has expired or is not yet valid
You can attempt to regenerate them using 'docker-machine regenerate-certs [name]
Afterwards I gave the docker-machine ls command a try in order to see if I could find something helpful. This is the output.

How can I fix it?

Answer 1

Try docker-machine regenerate-certs --client-certs.

Answer 2

Try this:
In your command prompt run:
docker-machine ls
it will return
NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS
<name> <status> <driver> <state> <url> <swarm> <docker> <errors>
get the <name> of the machine you want to run (if it's the first time you are running docker, then you have only one machine running and its name is default, in this example I will call it <name>)
then run:
docker-machine kill <name>
docker-machine create <name>
docker-machine env <name>
The last command will output more lines, copy the last one, in my case it was like this:
# eval $("C:\my\path\to\docker-machine.exe" env <name>)
then paste it in the command prompt without the # and run it, the problem should be fixed now.
You can check it by running docker-machine ls, if the problem is fixed, you should see no more messages under the ERROR column.
Furthermore, it is possible that the lines
docker-machine kill <name>
docker-machine create <name>
are not required if you have only one docker-machine existing and its <name> is default.

Maybe you can vi /etc/docker/daemon.json
use this setting:
{
"insecure-registries":[
"0.0.0.0/0"
]
}
then restart service:
service docker restart
and try again.
