I want to trigger remote Jenkins job from my container(k8s).
Currently, I'm using:
curl -k -X POST -u $USER:$JENKINS_TOKEN "${JENKINS_URL}/job/{$JOB_NAME}/buildWithParameters?token=12345"
But this information($USER,$JENKINS_TOKEN) is displayed in ArgoUI, is there any secure/other way to save credentials for remote trigger?
You can try one of the following.
Save the password in a file called password-file and read from that
curl -k -X POST -u $USER:$(cat .password-file)"${JENKINS_URL}/job/{$JOB_NAME}/buildWithParameters?token=12345"
Accept credentials from the STDIN.
curl -k -X POST "${JENKINS_URL}/job/{$JOB_NAME}/buildWithParameters?token=12345" -K- <<< "--user $USER:$JENKINS_TOKEN"
You can also try using --netrc-file option with curl where you can store the username and password in a file itself.
file
machine JENKINS_HOST login USERNAME password PASSWORD
Curl Command
curl -k -X POST --netrc-file my-password-file "${JENKINS_URL}/job/{$JOB_NAME}/buildWithParameters?token=12345"
I have created a declarative jenkins pipeline and one of it's stages is as follows:
stage('Docker Image'){
steps{
bat 'docker build -t HMT/demo-application:%BUILD_NUMBER% --no-cache -f Dockerfile .'
}
}
This is the docker file:
FROM tomcat:alpine
RUN wget -O /usr/local/tomcat/webapps/launchstation04.war http://localhost:8082/artifactory/demoArtifactory/com/demo/0.0.1-SNAPSHOT/demo-0.0.1-SNAPSHOT.war
EXPOSE 9100
CMD /usr/local/tomcat/bin/cataline.bat run
I am getting the below error.:
[91m/bin/sh:
01:33:28 [0mThe command '/bin/sh -c wget -O /usr/local/tomcat/webapps/launchstation04.war http://localhost:8082/artifactory/demoArtifactory/com/demo/0.0.1-SNAPSHOT/demo-0.0.1-SNAPSHOT.war' returned a non-zero code: 127
UPDATE:
I have updated the command to
RUN wget -O /usr/local/tomcat/webapps/launchstation04.war -U jenkinsuser:Learning#% http://localhost:8082/artifactory/demoArtifactory/com/demo/0.0.1-SNAPSHOT/demo-0.0.1-20200823.053346-18.war
There is no problem in my command.Jfrog artifactory was unable to authorize this action.So I added username and password details but it still didn't work.
Error:
wget: server returned error: HTTP/1.1 401 Unauthorized
It didnt work after modifiying the password policy to unsupported.But it worked when I allowed anonymous access.
How to provide access using credentials.
Need more clarification on your question. Not sure where you are using curl command.
Image tomcat:alpine doesn't contains curl command. Unless you install it manually.
bash-4.4# type curl
bash: type: curl: not found
bash-4.4#
If your ask is regarding the sh -c option, if the script is invoked through CMD option, yes it will use sh. Instead you can give a try with ENTRYPOINT.
You can provide username & password via command line:
wget --user user --password pass
Using curl :
curl -u username:password -O
But void using special characters:
Change your password to another once in: [a-z][A-Z][0-9]
Try an API Key instead of password, I have a feeling that "#" may be throwing you off. Quotes can help there too or separating the password with -p
Also look at the request logs for whether the entry comes as 401 for the user, or anonymous/unauthenticated
Lastly, see if you can cURL from outside the image and then ADD the file in, as that will remove any external factors that may vary from the host (where I assume the command works)
I'm working on some automation for Gerrit. I have used following API to check access
curl -X POST --digest -k --user username:password https://gitAccess/access/
But returns authentication required. Can you please help me
3 things to note as I was also getting an "unauthorized" when trying to access Gerrit APIs
Make sure you have your HTTP password. This is different from the
password you use to login to Gerrit. To get it, go to gerrit ->
click on your username -> Settings -> HTTP Password -> Click on
generate password. Use this password when making HTTP requests
Prefix /a to the endpoint URL as mentioned here. For example /changes becomes /a/changes when using authentication
Use the --digest option if you are using curl as mentioned here
Example
curl --digest -u <USERNAME> -i -H "Accept: application/json" "https://<GERRIT SERVER>/a/changes"
# curl will prompt you for the password. You can also do it as below
curl --digest --user <USERNAME:PASSWORD> -i -H "Accept: application/json" "https://<GERRIT SERVER>/a/changes"
I'm using docker registry v1 and I'm interested in migrating to the newer version, v2. But I need some way to get a list of images present on registry; for example with registry v1 I can execute a GET request to http://myregistry:5000/v1/search? and the result is:
{
"num_results": 2,
"query": "",
"results": [
{
"description": "",
"name": "deis/router"
},
{
"description": "",
"name": "deis/database"
}
]
}
But I can't find on official documentation something similar to get a list of image on registry. Anybody knows a way to do it on new version v2?
For the latest (as of 2015-07-31) version of Registry V2, you can get this image from DockerHub:
docker pull distribution/registry:master
List all repositories (effectively images):
curl -X GET https://myregistry:5000/v2/_catalog
> {"repositories":["redis","ubuntu"]}
List all tags for a repository:
curl -X GET https://myregistry:5000/v2/ubuntu/tags/list
> {"name":"ubuntu","tags":["14.04"]}
If the registry needs authentication you have to specify username and password in the curl command
curl -X GET -u <user>:<pass> https://myregistry:5000/v2/_catalog
curl -X GET -u <user>:<pass> https://myregistry:5000/v2/ubuntu/tags/list
you can search on
http://<ip/hostname>:<port>/v2/_catalog
Get catalogs
Default, registry api return 100 entries of catalog, there is the code:
When you curl the registry api:
curl --cacert domain.crt https://your.registry:5000/v2/_catalog
it equivalents with：
curl --cacert domain.crt https://your.registry:5000/v2/_catalog?n=100
This is a pagination methond.
When the sum of entries beyond 100, you can do in two ways:
First: give a bigger number
curl --cacert domain.crt https://your.registry:5000/v2/_catalog?n=2000
Second: parse the next linker url
curl --cacert domain.crt https://your.registry:5000/v2/_catalog
A link element contained in response header:
curl --cacert domain.crt https://your.registry:5000/v2/_catalog
response header:
Link: </v2/_catalog?last=pro-octopus-ws&n=100>; rel="next"
The link element have the last entry of this request, then you can request the next 'page':
curl --cacert domain.crt https://your.registry:5000/v2/_catalog?last=pro-octopus-ws
If the response header contains link element, you can do it in a loop.
Get Images
When you get the result of catalog, it like follows:
{
"repositories": [
"busybox",
"ceph/mds"
]
}
you can get the images in every catalog:
curl --cacert domain.crt https://your.registry:5000/v2/busybox/tags/list
returns:
{"name":"busybox","tags":["latest"]}
The latest version of Docker Registry available from https://github.com/docker/distribution supports Catalog API. (v2/_catalog). This allows for capability to search repositories
If interested, you can try docker image registry CLI I built to make it easy for using the search features in the new Docker Registry distribution (https://github.com/vivekjuneja/docker_registry_cli)
This has been driving me crazy, but I finally put all the pieces together. As of 1/25/2015, I've confirmed that it is possible to list the images in the docker V2 registry ( exactly as #jonatan mentioned, above. )
I would up-vote that answer, if I had the rep for it.
Instead, I'll expand on the answer. Since registry V2 is made with security in mind, I think it's appropriate to include how to set it up with a self signed cert, and run the container with that cert in order that an https call can be made to it with that cert:
This is the script I actually use to start the registry:
sudo docker stop registry
sudo docker rm -v registry
sudo docker run -d \
-p 5001:5001 \
-p 5000:5000 \
--restart=always \
--name registry \
-v /data/registry:/var/lib/registry \
-v /root/certs:/certs \
-e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt \
-e REGISTRY_HTTP_TLS_KEY=/certs/domain.key \
-e REGISTRY_HTTP_DEBUG_ADDR=':5001' \
registry:2.2.1
This may be obvious to some, but I always get mixed up with keys and certs. The file that needs to be referenced to make the call #jonaton mentions above**, is the domain.crt listed above. ( Since I put domain.crt in /root, I made a copy into the user directory where it could be accessed. )
curl --cacert ~/domain.crt https://myregistry:5000/v2/_catalog
> {"repositories":["redis","ubuntu"]}
**The command above has been changed: -X GET didn't actually work when I tried it.
Note: https://myregistry:5000 ( as above ) must match the domain given to the cert generated.
We wrote a CLI tool for this purpose: docker-ls It allows you to browse a docker registry and supports authentication via token or basic auth.
Here is a nice little one liner (uses JQ) to print out a list of Repos and associated tags.
If you dont have jq installed you can use: brew install jq
# This is my URL but you can use any
REPO_URL=10.230.47.94:443
curl -k -s -X GET https://$REPO_URL/v2/_catalog \
| jq '.repositories[]' \
| sort \
| xargs -I _ curl -s -k -X GET https://$REPO_URL/v2/_/tags/list
Install registry:2.1.1 or later (you can check the last one, here) and use GET /v2/_catalog to get list.
https://github.com/docker/distribution/blob/master/docs/spec/api.md#listing-repositories
Lista all images by Shell script example:
https://gist.github.com/OndrejP/a2386d08e5308b0776c0
I had to do the same here and the above works except I had to provide login details as it was a local docker repository.
It is as per the above but with supplying the username/password in the URL.
curl -k -X GET https://yourusername:yourpassword#theregistryURL/v2/_catalog
It comes back as unformatted JSON.
I piped it through the python formatter for ease of human reading, in case you would like to have it in this format.
curl -k -X GET https://yourusername:yourpassword#theregistryURL/v2/_catalog | python -m json.tool
Here's an example that lists all tags of all images on the registry. It handles a registry configured for HTTP Basic auth too.
THE_REGISTRY=localhost:5000
# Get username:password from docker configuration. You could
# inject these some other way instead if you wanted.
CREDS=$(jq -r ".[\"auths\"][\"$THE_REGISTRY\"][\"auth\"]" .docker/config.json | base64 -d)
curl -s --user $CREDS https://$THE_REGISTRY/v2/_catalog | \
jq -r '.["repositories"][]' | \
xargs -I #REPO# curl -s --user $CREDS https://$THE_REGISTRY/v2/#REPO#/tags/list | \
jq -M '.["name"] + ":" + .["tags"][]'
Explanation:
extract username:password from .docker/config.json
make a https request to the registry to list all "repositories"
filter the json result to a flat list of repository names
for each repository name:
make a https request to the registry to list all "tags" for that "repository"
filter the stream of result json objects, printing "repository":"tag" pairs for each tag found in each repository
Using "/v2/_catalog" and "/tags/list" endpoints you can't really list all the images. If you pushed a few different images and tagged them "latest" you can't really list the old images! You can still pull them if you refer to them using digest "docker pull ubuntu#sha256:ac13c5d2...". So the answer is - there is no way to list images you can only list tags which is not the same
I wrote an easy-to-use command line tool for listing images in various ways (like list all images, list all tags of those images, list all layers of those tags).
It also allows you to delete unused images in various ways, like delete only older tags of a single image or from all images etc. This is convenient when you are filling your registry from a CI server and want to keep only latest/stable versions.
It is written in python and does not need you to download bulky big custom registry images.
If some on get this far.
Taking what others have already said above. Here is a one-liner that puts the answer into a text file formatted, json.
curl "http://mydocker.registry.domain/v2/_catalog?n=2000" | jq . - > /tmp/registry.lst
This looks like
{
"repositories": [
"somerepo/somecontiner",
"somerepo_other/someothercontiner",
...
]
}
You might need to change the `?n=xxxx' to match how many containers you have.
Next is a way to automatically remove old and unused containers.
This threads dates back a long time, the most recents tools that one should consider are skopeo and crane.
skopeo supports signing and has many other features, while crane is a bit more minimalistic and I found it easier to integrate with in a simple shell script.
Docker search registry v2 functionality is currently not supported at the time of this writing. See discussion since Feb 2015: "propose registry search functionality #206" https://github.com/docker/distribution/issues/206
I wrote a script, view-private-registry, that you can find: https://github.com/BradleyA/Search-docker-registry-v2-script.1.0
It is not pretty but it gets the information needed from the private registry.
Example of output from view-private-registry:
$ view-private-registry`
busybox:latest
gcr.io/google_containers/etcd:2.0.9
gcr.io/google_containers/hyperkube:v0.21.2
gcr.io/google_containers/pause:0.8.0
google/cadvisor:latest
jenkins:latest
logstash:latest
mongo:latest
nginx:latest
python:2.7
redis:latest
registry:2.1.1
stackengine/controller:latest
tomcat:7
tomcat:latest
ubuntu:14.04.2
Number of images: 16
Disk space used: 1.7G /mnt/three/docker-registry/registry-data
One liner bash to list all images with their tags:
curl --user user:pass https://myregistry.com/v2/_catalog | jq .repositories | sed -n 's/[ ",]//gp' | xargs -L1 -IIMAGE curl -s --user user:pass https://myregistry.com/v2/IMAGE/tags/list | jq '. as $parent | .tags[] | $parent.name + ":" + . '
Two lines to search for something in the image name:
search=my_container_part_name
curl --user user:pass https://registry.medworx.io/v2/_catalog | jq .repositories | sed -n '/'"$search"'/{s/[ ",]//gp;}' | xargs -L1 -IIMAGE curl -s --user user:pass https://registry.medworx.io/v2/IMAGE/tags/list | jq '. as $parent | .tags[] | $parent.name + ":" + . '
replace: user, pass and myregistry.com accordingly
uses curl, sed, xargs and jq and is hard to understand... but it does the job. It produces one call per image + 1.
If you can ssh or attach to the docker registry container, just browse the filesystem to look for things you want, like:
kubectl exec -it docker-registry-0 -- /bin/sh
ls /var/lib/registry/docker/registry/v2/repositories
ls /var/lib/registry/docker/registry/v2/repositories/busybox/_manifests/tags/
Since each registry runs as a container the container ID has an associated log file ID-json.log this log file contains the vars.name=[image] and vars.reference=[tag]. A script can be used to extrapolate and print these. This is perhaps one method to list images pushed to registry V2-2.0.1.
If your use-case is identifying only SIGNED and TRUSTED images for production, then this method is handy.
It parses a docker image repo for all SIGNED tags and strips away all the JSON formatting, puking-out only clean image tags. Which of course can be processed further according to your requirements.
Format of Command:
docker trust inspect imageName | grep "SignedTag" | awk -F'"' '{print $4}'
Examples using the nginx & Bitnami Docker repos:
docker trust inspect nginx | grep "SignedTag" | awk -F'"' '{print $4}'
docker trust inspect bitnami/java | grep "SignedTag" | awk -F'"' '{print $4}'
If there are no signed images then No signatures or cannot access imageName will be returned.
Example of a repo WITHOUT signed images (at the time of this writing) using the Wordpress Docker repo:
docker trust inspect wordpress | grep "SignedTag" | awk -F'"' '{print $4}'
If you want a nice web interface to your registry you can use this registry-browser docker image. This is useful if you just want to look around your registry, different repositories and tags.
If, the accepted answer here only returns a blank line, it is likely because of your ssl/tls cert on your registry server. Use the --insecure flag:
curl --insecure https://<registryHostnameOrIP>:5000/v2/_catalog
